Richmond is a town in Tasmania about 25 km north-east of Hobart, in the Coal River region, between the Midland Highway and Tasman Highway. At the 2006 census, Richmond had a population of 880. Richmond's most famous landmark is the Richmond Bridge, built in 1823 to 1825, around the time of the town's first settlement. It is Australia's oldest bridge still in use. St John's Catholic church was built in 1836, and is considered the oldest Roman Catholic church in Australia. The town was initially part of the route between Hobart and Port Arthur until the Sorell Causeway was constructed in 1872.
