Venetian Gothic architecture
Venetian Gothic is the particular form of Italian Gothic architecture typical of Venice, originating in local building requirements, with some influence from Byzantine architecture, and some from Islamic architecture, reflecting Venice's trading network. Very unusually for medieval architecture, the style is at its most characteristic in secular buildings, with the great majority of surviving examples of the style being secular.
