The police station is thought to have been built shortly after 1845, the date of the original indentures. A very similar design can also be seen at the former police stations in Brynsiencyn and Llangefni. Menai Bridge Courthouse was built abutting the northern end c.1868 and doorways have been cut through to allow access between the two buildings. A later extension to the rear of both buildings encloses a small open area that was once part of a larger courtyard. Ceased to be used as a police station in 1959. Both buildings are now owned by the Independent Evangelical Church, who bought the premises in 1985 from Ynys Mon Borough Council.
