This lock was once used in the old 19th century gaol in Gilles Street, Warrnambool. The gaol is part of a group of four heritage buildings which comprise a police station, a police residence, police stables as well as the gaol. These were built between 1883 and 1888 from the designs of the Victorian Public Works Department architect, E.R. Laver. He was responsible for the designs of many 19th century country police stations, post offices and courthouses in Victoria. The four heritage buildings, of which the gaol is one, are important because they are some of the few surviving Warrnambool 19th century bluestone buildings. Today they form part of the South West Tafe Complex. This lock is of considerable interest as one used in the Warrnambool 19th century gaol building. The door on which it was used appears to be walled up now. This is a large iron lock with a base plate with three rivets and a projection piece. There are three curved iron pieces on the plate and these are fixed to the plate with 12 rivets. The bolt is rounded and moves under the three curved pieces across the plate. There are two other curved pieces, part of the bolt locking system. The lock has surface rust. warrnambool police and gaol heritage buildings, history of warrnambool
