The core of medieval Florence and more specifically the area between the church of “S. Martino” and “Piazza dei Donati”, was the 13th century location of the houses of the Alighieri family, as reported in many old documents. At the beginning of the 20th century, after several studies and researches, the Municipal Administration ordered the building of a house to celebrate the place of birth of Dante. Today, the building is the seat of the House-Museum of Dante, which was reopened to the public on June 1st, 1994. The museum is arranged on three floors according to the three most important stages in his life.
