The Doge's Palace was the residence of the Doge, the supreme authority of the Republic of Venice from 697 to 1797.The building of the palace, dating back to 1172, totally changed the original appearance of St Mark's Square, where it stands and has become one of its most famous attractions. Officially made a museum in 1923, the Doge's Palace has survived fires and floods in its long history, passing from hand to hand between different Doges. The façade, which overlooks the lagoon, is decorated with sculptures dating back to the 14th century. Six rooms of the palace are part of the Museo dell'Opera. They currently display undisputed masterpieces of Venetian sculpture, including the six original capitals and the 14th-century columns of the palace. Other notable highlights include the Doge's apartments, which offer a glimpse into the private life of the supreme leader of the Republic of Venice, and the Bridge of Sighs, one of the most famous bridges in Venice. Built in 1602, the bridge connects the Doge's Palace to the New Prisons. The Doge's Palace in Venice is open every day, from 9.00 am to 6.00 pm.
