One of the largest squares in Europe contains an entire artificial island.

A twisted steel beam from the wreckage of the World Trade Center is the centerpiece of this memorial for those who died on September 11, 2001.

One of the world's oldest working clocks is curiously missing the Zodiac sign of Libra.

The tomb of the mythological founder of Padua is not hidden in some obscure crypt, but stands right in the middle of the city square.
