Punnapra, is a village located near Alappuzha which has gone down into history as the battle ground between the Communists and the erst-while Travancore state police in the Punnappra- Vayalar Communist uprising of 1946. This uprising strengthened the approach of the people against the then Diwan of Travancore, Sir C.P. Ramaswamy Iyer, which finally led to his departure from the political scenario of Travancore. A memorial to the martyrs in Punnapra, stands testimony to the event, which the state Government declared as part of the freedom struggle. The Punnapra-Vayalar Riot tombs is situated at Kaithavana, 3Km away from Alappuzha Town.
