Site classified by the Historic buildings, Biot knew to preserve the authentic character of medieval village where each stone seems to reveal you a piece of his history. Medieval doors with the old covered way the visitor will have any leisure to discover the lanes on the unequal ground, the houses with the covered frontages of ivy spanning for better defending them, these narrow passages.

While reconsidering its steps, it reaches the door of Tines (1565) which leads to Rondon, then with punt forms panoramic, the street of the Goldsmiths and that of the Fish shop, to arrive at the heart of the village, on the place of the Arcades. Its architecture characteristic of galleries opening on the place by blind arcades in semicircular arch or warheads always astonishes the visitor.

With some steps the place of the Church with its polychrome pavement opens drawing two Maltese crosses. Rebuilt in XVème century, it contains two splendid tables: "the Virgin with the Rosary", allotted to Bréa (fine XVème century) and "Ecce Homo" allotted to Canavesio (XVIè century).
