Saint Markโ€™s Basilica in Venice flooded with nearly three feet of water last week, damaging part of the 1,000-year-old marble mosaic floor inside.

The basilica โ€œaged 20 years in one day,โ€ St. Markโ€™s procurator Carlo Tesserin said.
Floodwaters kept parts of the Madonna Nicopeia chapelโ€™s intricately designed floor under three feet of water for 16 hours. The chapel, located in the cathedral’s left transept, contains a 9th-century Byzantine icon of Mary.
The baptistry and the Zen Chapel, were completely flooded. The basilicaโ€™s bronze doors and columns also sustained damage. In St. Markโ€™s Basilicaโ€™s 926-year history, there have been only five floods as severe. The high watermark in Venice reached over 5 feet on Monday with an โ€œacqua alta,โ€ or high tide, covering 75 percent of the city.
