The Venetian Gothic Doge's Palace (Palazzo Ducale) is one of the main landmarks of the city of Venice. The palace was the residence of the Doge of Venice, the supreme authority of the former Republic of Venice, opening as a museum in 1923. Today, it is a museum.
In 810, Doge Angelo Partecipazio moved the seat of government from the island of Malamocco to the area of the present-day Rialto. However, no trace remains of that 9th-century building as the palace was partially destroyed in the 10th century by a fire. The following reconstruction works were undertaken at the behest of Doge Sebastiano Ziani (1172–1178). The new palace was built out of fortresses, one façade to the Piazzetta, the other overlooking the St. Mark's Basin. Although only few traces remain of that palace, some Byzantine-Venetian architecture characteristics can still be seen at the ground floor.
Political changes in the mid-13th century led to the need to re-think the palace's structure due to the considerable increase in the number of the Great Council's members. The new Gothic palace's constructions started around 1340, focusing mostly on the side of the building facing the lagoon. Only in 1424, did Doge Francesco Foscari decide to extend the rebuilding works to the wing overlooking the Piazzetta, serving as law-courts, and with a ground floor arcade on the outside, open first floor loggias running along the façade, and the internal courtyard side of the wing, completed with the construction of the Porta della Carta (1442).
The next reconstructions were made after a fire in 1483, 1547 and 1577. In the subsequent rebuilding work it was decided to respect the original Gothic style, despite the submission of a neo-classical alternative designs by the influential Renaissance architect Andrea Palladio.
Since 1996, the Doge’s Palace has been part of the Venetian museums network.
The north side of the courtyard is closed by the junction between the palace and St. Mark’s Basilica, which used to be the Doge’s chapel. At the center of the courtyard stand two well-heads dating from the mid-16th century.
In 1485, the Great Council decided that a ceremonial staircase should be built within the courtyard. The design envisaged a straight axis with the rounded Foscari Arch, with alternate bands of Istrian stone and red Verona marble, linking the staircase to the Porta della Carta, and thus producing one single monumental approach from the Piazza into the heart of the building. Since 1567, the Giants’ Staircase is guarded by Sansovino’s two colossal statues of Mars and Neptune, which represents Venice’s power by land and by sea, and therefore the reason for its name.References:
The city walls of Avila were built in the 11th century to protect the citizens from the Moors. They have been well maintained throughout the centuries and are now a major tourist attraction as well as a UNESCO World Heritage Site. Visitors can walk around about half of the length of the walls.
The layout of the city is an even quadrilateral with a perimeter of 2,516 m. Its walls, which consist in part of stones already used in earlier constructions, have an average thickness of 3 m. Access to the city is afforded by nine gates of different periods; twin 20 m high towers, linked by a semi-circular arch, flank the oldest ones, Puerta de San Vicente and Puerta del Alcázar.
