St. Mark's Campanile (Campanile di San Marco) is Venice's tallest structure at 98.6 meters, a red-brick bell tower in Piazza San Marco with an observation deck offering panoramic views of the city, lagoon, and on clear days, the Dolomites. The tower has served as the city's principal landmark since the original was first built in the 9th century. The tower you see today is technically a reconstruction. On July 14, 1902, the original campanile collapsed into a neat pile of rubble in Piazza San Marco, miraculously injuring no one (though a cat belonging to the custodian was the only casualty). The city council voted to rebuild it "com'era e dov'era" (as it was, where it was), and the replica was completed in 1912 using the same materials and dimensions. An elevator now takes visitors to the observation deck, which offers unobstructed views in every direction: the lagoon, the Lido, the rooftops of Venice, and on clear days, the Dolomites. At the tower's base stands the Loggetta, a small classical building designed by Jacopo Sansovino between 1537 and 1549. The Loggetta was originally a meeting place and later a guard post for arsenal workers during sessions of the Great Council. Its facade features four bronze statues by Sansovino (Minerva, Apollo, Mercury, and Peace) set in niches between composite columns. The Loggetta was crushed when the campanile fell in 1902 and was painstakingly reassembled from recovered fragments during the reconstruction. The bell tower holds five bells, each historically used to signal different events in Venetian public life, from the start of the workday to senate sessions to executions.
