St Mark's Basilica

The Patriarchate of Venice (Italian: Patriarcato di Venezia; Latin: Patriarchatus Venetiarum), also sometimes called the Archdiocese of Venice, is a patriarchate of the Latin Church of the Catholic Church, located in the Metropolitan City of Venice. Its episcopal seat is in the Cathedral Basilica of St. Mark in Venice. One of only four extant patriarchates in the Latin Church, its ordinary is the Patriarch of Venice, who is traditionally created a cardinal by the pope. Immediately upon installation in office, however, the Patriarch of Venice has the right to wear scarlet vesture (like a cardinal), whether or not he has yet been elevated to the College of Cardinals. As a metropolitan, the Patriarch of Venice is the metropolitan of the Ecclesiastical Province of Venice. Its suffragan dioceses include Adria-Rovigo, Belluno-Feltre, Chioggia, Concordia-Pordenone, Padova, Treviso, Verona, Vicenza, and Vittorio Veneto. In 1451 the Patriarchate of Grado was merged with the Bishopric of Castello and Venice to form the Patriarchate of Venice.

The Portrait of the Four Tetrarchs is a porphyry sculpture group of four Roman emperors dating from around 300 AD. The sculptural group has been fixed to a corner of the façade of St Mark's Basilica in Venice, Italy since the Middle Ages. It probably formed part of the decorations of the Philadelphion in Constantinople, and was removed to Venice in 1204 or soon after. Spolia from the Fourth Crusade, the statues were originally designed as two separate sculptures, each consisting of a pair of armoured late Roman emperors embracing one another. The paired statues stand on plinths supported by a console of the same stone, and their backs are engaged in the remains of large porphyry columns to which the statues were once attached, carved all of a piece. The columns no longer exist, and one emperor pair is missing part of the plinth and an emperor's foot, which has been found in Istanbul. One statue pair has been sliced vertically and is missing a large portion of the right-hand emperor's right side, while another vertical slice divides the two figures and has sawn through their embracing arms. The Portrait of the Four Tetrarchs probably depicts the four rulers of the Empire instituted by Emperor Diocletian – the first Tetrarchy. He appointed as co-augustus Maximian; they chose Galerius and Constantius I as their caesares; Constantius was father to Constantine the Great. There is disagreement as to the identity of these statues and their placement, but it is suggested that the Eastern rulers form a pair and the Western rulers form the other pair, each pair consisting of the senior augustus and the junior caesar. Another possibility is that the two augusti are depicted in one pair and the two caesares in the other. A third, older theory is that they represent a dynastic group of the Constantinian dynasty.

The Horses of Saint Mark (Italian: Cavalli di San Marco), also known as the Triumphal Quadriga or Horses of the Hippodrome of Constantinople, is a set of bronze statues of four horses, originally part of a monument depicting a quadriga (a four-horse carriage used for chariot racing). The horses were placed on the facade, on the loggia above the porch, of St Mark's Basilica in Venice, northern Italy after the sack and looting of Constantinople in 1204. They remained there until looted by Napoleon in 1797 but were returned in 1815. The sculptures have been removed from the facade and placed in the interior of St Mark's for conservation purposes, with replicas in their position on the loggia.

Piazzetta dei Leoncini is a city square in Venice, Italy. The square is located on the north side of the St Mark's Basilica, near the Palazzo Patriarcale and San Basso. The square is known for its lion statuary. Also on the square, in an alcove of the Basilica itself, is the sarcophagus of Daniele Manin, the president of the brief independent Republic of San Marco, established during a rebellion in 1848 against Habsburg rule.

The Doge's Palace (Italian: Palazzo Ducale; Venetian: Pałaso Dogal) is a palace built in Venetian Gothic style, and one of the main landmarks of the city of Venice in northern Italy. The palace was the residence of the Doge of Venice, the supreme authority of the former Republic of Venice. It was built in 1340 and extended and modified in the following centuries. It became a museum in 1923 and is one of the 11 museums run by the Fondazione Musei Civici di Venezia.

San Basso is a Baroque style deconsecrated Roman Catholic church in central Venice, Italy; it now serves as a concert hall. According to the Venetian historian Flaminio Corner, the church was erected in the year 1079. It was rebuilt after fires in 1105 and again in 1661, the latter to a design by Baldassarre Longhena. Located nearby the St. Mark's Clocktower, it has a side façade on the Piazza San Marco. It has four Corinthian columns and two single mullioned windows. In 1806, during the Napoleonic occupation, the church was closed and sold to a private source. In 1847 it was ceded to the Basilica di San Marco, which used it to store marbles and sculptures until, in the 1890s, it was restored as a meeting and concert hall.

St Mark's Clock is housed in the Clock Tower on the Piazza San Marco (Saint Mark's Square) in Venice, Italy, adjoining the Procuratie Vecchie. The first clock housed in the tower was built and installed by Gian Paolo and Gian Carlo Rainieri, father and son, between 1496 and 1499, and was one of a number of large public astronomical clocks erected throughout Europe during the 14th and 15th centuries. The clock has had an eventful horological history, and been the subject of many restorations, some controversial. After restorations in 1551 by Giuseppe Mazzoleni, and in 1615, by Giovanni Battista Santi, the clock mechanism was almost completely replaced in the 1750s, by Bartolomeo Ferracina. In 1858 the clock was restored by Luigi De Lucia. In 1996, a major restoration, undertaken by Giuseppe Brusa and Alberto Gorla, was the subject of controversy, amid claims of unsympathetic restoration and poor workmanship.

St Mark's Campanile (Italian: Campanile di San Marco, Venetian: Canpanièl de San Marco) is the bell tower of St Mark's Basilica in Venice, Italy. The current campanile is a reconstruction completed in 1912, the previous tower having collapsed in 1902. At 98.6 metres (323 ft) in height, it is the tallest structure in Venice and is colloquially termed "el paròn de casa" (the master of the house). It is one of the most recognizable symbols of the city.Located in Saint Mark's Square near the mouth of the Grand Canal, the campanile was initially intended as a watchtower to sight approaching ships and protect the entry to the city. It also served as a landmark to guide Venetian ships safely into harbour. Construction began in the early tenth century and continued sporadically over time as the tower was slowly raised in height. A belfry and a spire were first added in the twelfth century. In the fourteenth century the spire was gilded, making the tower visible to distant ships in the Adriatic. The campanile reached its full height in 1514 when the belfry and spire were completely rebuilt on the basis of an earlier Renaissance design by Giorgio Spavento. Historically, the bells served to regulate the civic and religious life of Venice, marking the beginning, pauses, and end of the work day; the convocation of government assemblies; and public executions. The campanile stands alone in the square, near the front of St Mark's Basilica. It has a simple form, recalling its early defensive function, the bulk of which is a square brick shaft with lesenes, 12 metres (39 ft) wide on each side and 50 metres (160 ft) tall. The belfry is topped by an attic with effigies of the Lion of St Mark and allegorical figures of Venice as Justice. The tower is capped by a pyramidal spire at the top of which there is a golden weather vane in the form of the archangel Gabriel.

The Loggetta is a small, richly decorated building at the base of the bell tower in Saint Mark's Square, Venice, Italy. Built by Jacopo Sansovino between 1538 and 1546, it served at various times as a gathering place for nobles and for meetings of the procurators of Saint Mark, the officials of the Venetian Republic who were responsible principally for the administration of the treasury of the Church of Saint Mark and for the public buildings around Saint Mark's Square. Because of its location directly in front of the Porta della Carta, the most important entry to the Doge's Palace, the loggetta was also used from 1569 onward as a sentry post to provide security for the assembled nobles during the meetings of the Great Council: three procurators were to be present, assisted by an armed squadron of workers from the Arsenal, the government shipyard, in order to counter any popular assault and respond to any fire. Beginning in 1734, it was additionally the site for the extraction of winning tickets in the public lottery.The loggetta was largely destroyed in the collapse of the bell tower in 1902, but it was rebuilt using what original material could be salvaged, amounting to about half of the present building. At the same time the sides, which had originally been left in plain brick as other lean-to structures backed onto them, were rebuilt in the style of the main facade. The building serves as the entrance to the tower elevator.

The Clock Tower in Venice is an early Renaissance building on the north side of the Piazza San Marco, at the entrance to the Merceria. It comprises a tower, which contains the clock, and lower buildings on each side. It adjoins the eastern end of the Procuratie Vecchie. Both the tower and the clock date from the last decade of the 15th century, though the mechanism of the clock has subsequently been much altered. It was placed where the clock would be visible from the waters of the lagoon and give notice to everyone of the wealth and glory of Venice. The lower two floors of the tower make a monumental archway into the main street of the city, the Merceria, which linked the political and religious centre (the Piazza) with the commercial and financial centre (the Rialto). Today it is one of the 11 venues managed by the Fondazione Musei Civici di Venezia.

The National Archaeological Museum (Italian: Museo Archeologico Nazionale di Venezia) is a museum located right on Piazza San Marco in Venice.
