Filippo Calendario

The facade of the Doge's Palace, Venice, clearly showing the two building phases.

Filippo Calendario (died 16 April 1355 in Venice, Italy) was an architect, a designer of the 14th century Doge's Palace, Venice. He was executed for treason.

Design of Doge's Palace By the end of the 13th century the existing Doge's Palace in Venice needed enlarging. Rebuilding commenced around 1340, though interrupted for several years because of the plague.

Calendario is attributed by some sources as the first architect or, at least, a collaborator. Calendario first appears in official records in 1340, when he is described as a master of two small boats, used to transport stone for construction. By 1341 he was the owner of five boats. This makes it likely he was also a stonemason. However, the Palace is noticeably built in two phases, believed to be because of Calendario's execution.
