The New Parliament was inaugurated on 29 April 1982. The buildings were built on reclaimed land, after a massive lake was formed by dredging the marshlands around the Diyawanna Oya. The new parliamentary buildings were built on Duwa, a 50,000 square metre (12 acre) island in the centre of the lake. The island (off Baddegana Road, Pita Kotte) had been used as a recreation and brawling spot for Portuguese soldiers in the last days of the Kotte era, alcohol being banned from the Royal City. It had belonged to E. W. Perera and had housed a chicken farm prior to being vested in the state. On 29 April 1982, the new parliamentary complex was declared open by the former president J. R. Jayewardene.
