Kamerlengo Castle: the Venetian fortress guarding Trogir's harbour
Kamerlengo Castle is a fortress at the south-western corner of the old town of Trogir, on the Dalmatian coast west of Split. Built by the Venetians between 1420 and 1437 around an older tower, it was designed to defend the sea channel and the approach to the harbour. Today it is a quiet stone landmark on the seafront and, in summer, a venue for performances.
Trogir's new Venetian rulers did not trust the townspeople, so within a few years of conquering the town they built a castle to rule it from. Its name still means “chamberlain”.
The history of Kamerlengo Castle
The story begins in the late 14th century, when a polygonal corner tower known as the Veriga Tower (the Tower of Chains) was raised at the south-western edge of Trogir's town walls. It is the oldest part of what later became Kamerlengo Castle.
Everything changed in 1420, when the Republic of Venice conquered Trogir after a siege of almost two months. The city's defences were badly damaged and its people were hostile to their new lords, so the Venetians decided they needed a castle from which to govern. Between 1420 and 1437 they built the fortress, and the former corner tower of the walls became its keep. Croatian sources name the master builder as Marin Radoj, while a state engineer was consulted on the design.
The new stronghold was meant to defend the sea channel and the approach to the harbour. Originally it was separated from the town by an outer crenellated wall and a wet moat, and a wide moat ran along the north and east sides. It housed the Venetian mercenaries and their kamerlengo, an administrative official whose title translates as chamberlain or governor. At first it was known simply as the castle of Trogir; only from the middle of the 16th century did it become Kamerlengo Castle.
The courtyard held houses for the castellan and the garrison, and a small chapel dedicated to St Mark, patron saint of the Venetian Republic. A monumental relief of a lion, the symbol of St Mark, was set above it, with a smaller relief showing the coat of arms of the Tron family. Luka Tron served as city prince of Trogir from 1421 to 1424. A Gothic lion with the initials DC and the arms of the Contarini family recalls Doge Domenico Contarini I. The outer walls were once decorated with the coats of arms of the admiral Pietro Loredan, Doge Francesco Foscari and Trogir's prince Magdaleno Contarini.
In the mid-19th century most of Trogir's town walls were demolished and the castle moat was filled in. There were even plans to pull down the dilapidated castle, but they were prevented. Today the fortress serves as a venue for performances during the summer months.
