The circular Baptistery in Pisa is the largest of its kind in Italy, with a circumference of 104 metres / 348 feet.
The building commenced in 1153 by Deotisalvi. More than 100 years later, it was worked on further and the upper part was created in a rather Gothic style and a large dome was added shortly after. The vast interior is fairly plain and features one of the first great Pisano pulpits, sculpted in 1260 by Nicola Pisano and a massive, carved font.

One of the most interesting features in the Baptistery is the simply astonishing acoustics, which echo around the interior. To enjoy these wonderful acoustics it is worth arriving early in the morning, before the building gets too busy. When a choir sings in the Pisa Baptistery it is memorable to say the least.
