You reach it down a narrow staircase, usually starting from the family cellar: a few square metres carved by hand into the rock, with no windows, no light and no ventilation. It is called an <strong>infernot<\/strong>, and since 2014 it has been part of the UNESCO World Heritage. Here is what it is, why it exists only in this corner of Italy, and how to get inside one.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What an infernot actually is<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">An infernot is a small underground chamber dug into <strong>pietra da cantoni<\/strong>, hollowed out below the house and usually connected to the family cellar. It has no opening to the outside: no windows, no air vents, no equipment of any kind. That complete enclosure is precisely what makes it work, because temperature and humidity stay almost constant all year round, with no swing between summer and winter.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">They are small, rarely more than a few square metres, and the furniture amounts to niches and shelves carved out of the rock itself, where bottles lie on their side. Many have a barrel vault, some a central pillar, others a little decoration cut into the stone by whoever dug them. These were homemade jobs, done by hand for one household: no two infernot are alike.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why they exist only here: the pietra da cantoni<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The reason is geological. Millions of years ago the Monferrato was a sea floor, and those marine sediments produced the pietra da cantoni, a marly limestone sandstone that formed around twenty million years ago and surfaces in the countryside around Casale Monferrato. It has one property that makes it perfect for the job: it is <strong>soft when quarried<\/strong>, soft enough to be cut with hand tools, and it <strong>hardens on exposure to air<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In practice, a farmer could dig himself a room under his own house with no machinery and no shoring, and end up with walls that grew solid on their own over time. You can read the same stone above ground the moment you walk into a village like <a href=\"https:\/\/www.agriturismi.it\/en\/cella_monte\">Cella Monte<\/a>: house fronts, doorways, vineyard retaining walls and churches all share the same pale straw colour.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">They are not wine cellars<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">This is the common misunderstanding. An infernot <strong>is not a working cellar<\/strong>: no wine is made there, no barrels are kept there, no work is done there. It is a private store \u2014 the place where a family sets aside its best bottles, the ones meant to be kept for years and opened on the right occasion. House vintages, the wedding wine, the reserves.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That explains both why there are so many of them and why they are all small: they come not from an industry but from a domestic habit repeated house by house. The survey run by the Ecomuseum of Pietra da Cantoni counts <strong>47 of them across fourteen municipalities<\/strong>. Many more remain private and closed to visitors, walled up or simply still in use by the family living above.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">&#8220;The Monferrato of the Infernot&#8221;, a UNESCO site since 2014<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">On 22 June 2014 the <em>Vineyard Landscape of Piedmont: Langhe-Roero and Monferrato<\/em> became the fiftieth Italian site inscribed on the UNESCO World Heritage List. The inscription is made up of six components, and one of them is named exactly that: <strong>&#8220;The Monferrato of the Infernot&#8221;<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The core zone covers nine municipalities, all in the province of <a href=\"https:\/\/www.agriturismi.it\/en\/alessandria\">Alessandria<\/a>: Camagna Monferrato, Cella Monte, Frassinello Monferrato, Olivola, Ottiglio, Ozzano Monferrato, Rosignano Monferrato, Sala Monferrato and <a href=\"https:\/\/www.agriturismi.it\/en\/vignale_monferrato\">Vignale Monferrato<\/a>. It is a compact area, easily driven in a day, made of villages of a few hundred people sitting on hilltops with vineyards running down the slopes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It is worth noting that the listing does not reward individual monuments but the <strong>landscape as a whole<\/strong>: the relationship between the vine, the stone quarried from the same hill, and the way people have lived on it. The infernot is the part of that landscape that sits underground.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to visit one<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">This is the part to arrange before you set off, because <strong>almost no infernot can simply be walked into<\/strong>. Nearly all are private or municipally owned and are opened by appointment or on scheduled days. Turning up in a village hoping to find one open does not usually work.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Ecomuseum of Pietra da Cantoni<\/strong>, in Cella Monte: it occupies Palazzo Volta, a sixteenth-century building with a loggia, and keeps an infernot open to visitors. It is the natural starting point, not least to have the local geology explained before you go underground. Visits are booked through the ecomuseum, which also coordinates access to the other infernot.<\/li>\n<li><strong>Booked openings<\/strong>: in the usual season visits run on Friday and Saturday by appointment, with some Sunday openings. Times change through the year, so always check and book ahead, especially on autumn weekends.<\/li>\n<li><strong>The infernot of Palazzo Callori<\/strong>, in Vignale Monferrato: the palace of the counts of Vignale now houses the Regional Wine Cellar of Monferrato, with one of the best-known infernot of the area in its basement.<\/li>\n<li><strong>Farm stays and wineries<\/strong>: a good number of local farms have their own infernot under the house and show it to guests along with the cellar. It is often the easiest way to see one \u2014 and the most authentic, because it is still in use.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">One practical note: these are underground rooms, cool even in August, reached by steep and sometimes slippery steps. Closed shoes and a sweater are a good idea even when it is thirty degrees outside.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What else is nearby<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The infernot themselves fill half a day; the point of the trip is the country around them. Within a twenty-kilometre radius you have <a href=\"https:\/\/www.agriturismi.it\/en\/moncalvo\">Moncalvo<\/a>, officially the smallest city in Italy, which hosts the National White Truffle Fair in October \u2014 second in Piedmont only to Alba&#8217;s; the Sacred Mount of Crea, a UNESCO site since 2003, with twenty-three chapels along a path through the woods; and the abbey of Grazzano Badoglio, burial place of Aleramo, founder of the line of the marquises of Monferrato.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">We have put all of these together into a loop of roughly seventy kilometres: <a href=\"https:\/\/www.agriturismi.it\/en\/routes\/focus\/moncalvo_and_the_infernot_of_monferrato\"><strong>Moncalvo and the Infernot of Monferrato<\/strong><\/a>, seven stages from Cocconato to Vignale with a map and notes on each village.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In the glass, this is the country of Grignolino del Monferrato Casalese \u2014 a pale-coloured, tannic red that surprises anyone expecting something light \u2014 along with Barbera del Monferrato and Freisa. At the table: <em>agnolotti al plin<\/em>, veal with tuna sauce, <em>bagna cauda<\/em> from autumn onwards, robiola cheese and krumiri biscuits.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Where it is and how to get there<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The Monferrato of the Infernot lies in <strong>Piedmont<\/strong>, north-west Italy, across the provinces of <a href=\"https:\/\/www.agriturismi.it\/en\/alessandria\">Alessandria<\/a> and <a href=\"https:\/\/www.agriturismi.it\/en\/asti\">Asti<\/a>, in the belt of hills between Casale Monferrato to the north and Asti to the south. The geographic centre of the area is <a href=\"https:\/\/www.agriturismi.it\/en\/cella_monte\">Cella Monte<\/a> (45.074\u00b0 N, 8.392\u00b0 E), at around 200 metres above sea level.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>By car<\/strong>: about 10 km from Casale Monferrato, 30 from Asti, 35 from Alessandria, 70 from Turin, 100 from Milan and 110 from Genoa. The handiest motorway exit is Casale Monferrato on the A26.<\/li>\n<li><strong>By train<\/strong>: the reference station is Casale Monferrato; from there you need a car or a taxi, as the core-zone villages have no station of their own.<\/li>\n<li><strong>By air<\/strong>: Turin Caselle is about 80 km away, Milan Malpensa about 85 km.<\/li>\n<li><strong>Getting around<\/strong>: narrow, winding provincial roads with constant ups and downs. Distances are short but journey times are not: allow 15 to 20 minutes between one village and the next.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">When to go<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">April and May bring green hills and long days. September is the grape harvest, with the wineries in full swing. October and November are probably the best window: white truffle, village fairs, and the vineyards turning yellow and red. August is quiet enough, but several producers close for the holidays, so call ahead.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Where to stay: farmhouses in Monferrato<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Farm stays in the Monferrato are hillside farmhouses among the vineyards, often with their own cellar and with the same pietra da cantoni in the walls. Many have an infernot below the house. They cost less than hotels in Asti or Casale, and they offer what actually matters here: someone who knows the back roads, the right wineries and the numbers to call to book a visit.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You can browse the available properties in <a href=\"https:\/\/www.agriturismi.it\/en\/piedmont\">Piedmont<\/a>, or narrow the search to the provinces of <a href=\"https:\/\/www.agriturismi.it\/en\/alessandria\">Alessandria<\/a> and <a href=\"https:\/\/www.agriturismi.it\/en\/asti\">Asti<\/a>, which between them share the Monferrato.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Frequently asked questions about the infernot<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">What is an infernot?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">An infernot is a small underground chamber dug by hand into pietra da cantoni, hollowed out beneath the house and with no light, windows or ventilation. It keeps the family&#8217;s bottles at constant temperature and humidity. Infernot are found in the Monferrato hills near Casale Monferrato, in Piedmont, and have been a UNESCO World Heritage site since 2014.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Why do infernot exist only in Monferrato?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The reason is geological. Pietra da cantoni, a marly limestone sandstone formed from marine sediments around twenty million years ago, is soft when quarried and hardens on exposure to air. That allows a room to be cut with hand tools while the walls grow solid over time. The stone surfaces only in the countryside around Casale Monferrato.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Which villages make up the UNESCO &#8220;Monferrato of the Infernot&#8221;?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The core zone covers nine municipalities in the province of Alessandria: Camagna Monferrato, Cella Monte, Frassinello Monferrato, Olivola, Ottiglio, Ozzano Monferrato, Rosignano Monferrato, Sala Monferrato and Vignale Monferrato. They form one of the six components of the UNESCO site &#8220;Vineyard Landscape of Piedmont: Langhe-Roero and Monferrato&#8221;, inscribed on 22 June 2014.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How many infernot are there, and can they be visited?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The survey by the Ecomuseum of Pietra da Cantoni counts 47 across fourteen municipalities. Nearly all are private or municipally owned and can be visited by appointment only: the reference point is the Ecomuseum of Pietra da Cantoni in Cella Monte, housed in Palazzo Volta, which keeps an infernot open to visitors and coordinates access to the others.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What is the difference between an infernot and a wine cellar?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">An infernot is not a working cellar: no wine is made there and no barrels are kept there. It is a private store where a family keeps its best bottles to age. It is smaller than a cellar, has no opening to the outside, and is usually entered from the house cellar itself.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">When is the best time to visit Monferrato?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">April and May for green hills and long days, September for the grape harvest, October and November for white truffle, village fairs and the autumn colour of the vineyards. August is quiet, but several wineries close for the holidays, so call ahead.<\/p>\n\n\n\n<script type=\"application\/ld+json\">\n{\"@context\":\"https:\/\/schema.org\",\"@type\":\"FAQPage\",\"mainEntity\":[\n{\"@type\":\"Question\",\"name\":\"What is an infernot?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"An infernot is a small underground chamber dug by hand into pietra da cantoni, hollowed out beneath the house and with no light, windows or ventilation.
