The town of Certaldo is divided into upper and lower parts. The lower part is called Certaldo Basso, whilst the medieval upper part is called called Certaldo Alto. Certaldo Alto has limited vehicular access, for use by residents only, and is linked to Certaldo Basso by the Certaldo funicular.
Boccaccio's house, of red brick, like the other old houses here, was restored in 1823 and furnished with old furniture. A statue of him was erected in the main square in 1875.
The Palazzo Pretorio, or Vicariale, the residence of the Florentine governors, recently restored to its original condition, has a picturesque facade adorned with ceramic coats of arms, and in the interior are various frescoes dating from the 13th to the 16th century.
The town hosts several festivals a year. The largest and most famous is Mercantia, a week-long party in Certaldo Alto. It involves numerous street performers from across Italy, Europe and even the Americas.
