The underground cathedrals
The underground cathedrals are the historic cellars of Canelli, about 15km from the hotel. They are cellars dug into the tufa in past centuries that go down to 32 meters underground through the entire Canelli hill and the entire city for more than 20 km. They are called Cathedrals because they create surreal and evocative environments and are real masterpieces of engineering and wine-making architecture.
Thousands of bottles of fine wine are left to ferment there at a constant temperature of 12-14 degrees, to take on the aromas and flavours typical of sparkling wine and of the Canelli wine in cells with vaulted brick ceilings dating back to the early nineteenth century. They have recently been included in the list of UNESCO World Heritage Sites, as part of the city of Canelliassieme with similar constructions called there Infernot, being unique goods and not traceable in no other place in the world (a basic requirement for admission), and being admitted concurrently with that of the larger territories (to which they belong) of Monferrato, Roero and Langhe.
