A Venetian tower built sometime around the end of the 17th century. In 1802, it was renovated by Spyridon Markellos, a fighter, later, of the Greek Revolution and member of the Filiki society.

During the revolution, the building hosted Greek and foreign activists and politicians. Between 1826 and 1828 the tower functioned as the seat of government and later, when Aegina was briefly the capital of the new state, housed a number of ministers and the State Treasury.

Today the tower belongs to the Municipality of Aegina and is home of the island’s Kapodistrian Cultural Centre. It also hosts a variety of painting exhibitions, lectures and other cultural events, as well as the Spyros Alexiou Social Awareness Centre.
