An elevator whisks you to the top of this 97m (318-ft.) brown brick bell tower where you get awe-inspiring views of St. Mark’s cupolas. With a gilded angel atop its spire, it is the highest structure in the city, offering a pigeon’s-eye panorama that includes the lagoon, neighboring islands, and the red rooftops and church domes of Venice. Originally built in the 9th century, the bell tower was reconstructed in the 12th, 14th, and 16th centuries, when the pretty marble loggia at its base was added by Jacopo Sansovino. It collapsed unexpectedly in 1902, miraculously hurting no one except a cat. It was rebuilt exactly as before, using most of the same materials, even one of the five historical bells that it still uses today.
