Camillo Camilliani (fl. 1574–1603) was an Italian architect, military engineer and sculptor. He is mostly known for the design of watchtowers and other fortifications around the coasts of Sicily.

Camillani was born in Florence sometime in the 16th century. He was the son of the sculptor Francesco Camilliani. In 1574, he and Michelangelo Naccherino directed the relocation of the Fontana Pretoria, which had been designed by his father, from Florence to Palermo.^[1]

In July 1583, Viceroy Marcantonio Colonna invited him to Sicily to design a system of coastal fortifications to prevent the island from being attacked by the Ottoman Empire or Barbary pirates. Camillani reviewed the existing fortifications, and in 1584 he published his findings in the report Descrittione delle marine di tutto il regno di Sicilia con le guardie necessarie da cavallo e da piedi che vi si tengono.

He went on to design watchtowers, which were built at strategic sites along the coastline, in such a way that they were able to communicate with each other and warn cities of any approaching enemy. The towers had a square base with two floors, and were armed with artillery pieces on the roof.

Camillani also designed fountains, statues and funerary monuments for various patrons and churches.^[2]

Camillani designed the following buildings, among others:
