Leaning Tower of Pisa

The Leaning Tower doesn't lean so much anymore. It now leans like it did in 1838.

"It has straightened a little bit more than we expected, but every little helps," said Prof John Burland, an expert in soil mechanics at Imperial College London, who was the only British member of the 14-strong rescue committee.

He said the tower was still "very slightly moving" towards being upright, but that it had stabilised.

The tower, which has been leaning almost since building work first began in 1173, was closed to the public in 1990 because of safety fears. The 183-foot tower was nearly 15 feet off vertical and its structure was found to have been weakened by centuries of strain.
