A fortress built to guard the access by the river Arno and the shipyard in the middle age, when the sea was closer to the city.
A very small Gothic church built in 1230 to house a thorn from Jesus's crown, it's considered one of the best expressions of Italian Gothic. It is so small that in 1800, it was moved from the Arno riverbank to a place some metres higher, one stone at time, to protect it from flooding. It's usually not open to the public.
Orto botanico
The first university botanical garden in Europe, created by the will of Cosimo de' Medici in 1544.
Skipped over by many visitors, this museum is a treat for art lovers. After World War II many of the surviving murals and pieces of murals from Pisa's Campo Santo were detached from the walls to try to preserve them. It was unexpectedly discovered that the artist sketches underneath survived. These were moved to this museum.
Monumental Cemetery
A huge cemetery building with lots of interesting art, including a collection of ancient Roman sarcophagi and splendid medieval frescoes by the "Master of the Triumph of Death". There is also a 19th-century statue of the famous mathematician Leonardo Fibonacci, a native of the city.
Baptistry of St. John
Large round Romanesque dome with many sculptured decorations and a fine view up top; climb this if you want a great view with the Leaning Tower visible in your photos. Arabic-style pavement, pulpit by Nicola Pisano (father of Giovanni), and fine octagonal font. At regular intervals, the ticket-checker-guard at the entrance comes into the baptistery and gives an audio-treat of echo-effect. The guard shouts out few sounds which when echoed sound like pure beautiful music. You can also cast your inhibitions to the wind, stand by the wall, and sing long notes that turn into chords by yourself, as the echoes go round and round the dome of the building.
