The first Loggia in Chandax was built in the mid-13th century, though no evidence survives as to its precise location. According to the Venetian Archives, in 1325 the nobles and feudal lords of Chandax applied to Venice for a grant of land near the square to build a new Loggia, since the existing one was "much too exposed to the wind, particularly in winter." The application was approved and land was indeed granted next to the square for the erection of the second Loggia.

It was in that building that the events surrounding the insurrection of 1363 must have taken place. At the time, Venetian feudal lords opposed to the oppressive tax imposed by the mother city forced their way into the Loggia, took the officially appointed Venetian rulers hostage and declared the St. Titus Republic.

Yet this building also fell into ruin, and in 1541 a third Loggia was built, possibly to plans by Michele Sanmicheli. It was smaller than the previous one, occupying approximately half the land area of the one that replaced it in 1628, which was to be the town's last Venetian nobles' club.
