It is said that Napoleon called San Marco "the drawing room of Europe." And it is a breathtakingly beautiful place. But the square has long been a lure for massive numbers of pigeons, drawn by the massive numbers of tourists who readily feed them. While the tourists happily post for photos amid the flock, there are concerns that the birds' presence--and what they leave behind--will damage the centuries old architecture and art work.

Blending the architectural styles of East and West, Venice's magnificent basilica was consecrated in 832 AD as an ecclesiastical building to house the remains of St. Mark.

A masterpiece of Gothic architecture, the building and its sculptural decoration date from various periods. The interior, with works by artists such as Titian, Veronese, Tintoretto, A.Vittoria and Tiepolo, includes vast council chambers, superbly decorated residential apartments, and austere prison cells. Along the facades of the Palace run loggias that overlook St. Mark’s Square and the lagoon. The combined entrance ticket to the St. Mark’s Square Museums grants access to the Doge’s Palace, Museo Correr, Museo Archeologico Nazionale and Monumental Rooms of Biblioteca Marciana.

Originally built as a lighthouse to assist navigation in the lagoon, visitors can be whisked by elevator to the top of St. Mark's Campanile or bell tower to savor incredible views of Venice, the lagoon and the Alps in the distance.

This satellite gallery of the famous Guggenheim in New York occupies the 17th-century Customs House in Venice, featuring modern and contemporary works of art.

The northernmost of Venice's six sestieri (districts) is where the former Jewish ghetto was located. The main street, Strada Nuova, is often bursting with activity.
