On to one side of Constitution Square is the Parliament Building. Originally built in 1730 for use as a Mosque.

After the Victory of the Greek War of Independence in1821 it was to be the housing for the 1st Liberated Greek Parliament.

When the capital was moved to Athens, followed the Parliament.

Since then the building has been used as many things including a school, dance hall and a court where the trials of the Generals Kolokotronis and Plapoutas were held.

Today the 1st Parliament Building has been restored and is used for conferences and cultural exhibitions.
