The Patriarchal Cathedral Basilica of Saint Mark officially known in Italian as the Basilica Cattedrale Patriarcale di San Marco and commonly known as Saint Mark’s Basilica is the cathedral church of the Roman Catholic Archdiocese of Venice, northern Italy.

It is the most famous of the many churches of Venice and one of the finest examples of Italo-Byzantine architecture.

The relics were initially housed in a temporary chapel within the Doge’s Palace, but a more substantial church was built to shelter the valuable relics in 828-832

The church burned down in 976 during an uprising.

It was restored under his successor, Doge Domenico Contarini (died about 1070).

The present basilica was completed in 1071.


The plan is a Greek cross, and the building is surmounted by five domes. The design is distinctly Byzantine, and it is likely that both Byzantine and Italian architects and craftsmen were employed in the construction and decoration.

Over the centuries, additions of sculpture, mosaics, and ceremonial objects have increased the church’s richness.

It was the doge’s private chapel until 1807, when it became the city’s cathedral.

The exterior of the west facade of the basilica is divided in three registers: lower, upper, and domes.
