Your attention will be drawn to a well-preserved mosque in the north west part of Syntagma Square. It is the Parliament Building, the first Parliament of Greece. It was built in 1730 as a mosque with a large hall and characteristic dome. Between autumn 1825 and spring 1826, it housed the first Parliament of Greece, which is why it is called Parliament.
According to local tradition, the mosque was built by the Ottoman, Aga Pasa, in an attempt to redeem himself for killing two Venetians who had come to Nafplio to discover the treasure he had hidden from the Second Venetian period. With the treasure he himself discovered, he paid for the construction of the building, though he did not live to see its completion as he was washed away by remorse by jumping from the gallery.
Today the building is used for conferences, lectures, exhibitions, concerts and other cultural events.
