Linenhall Arts Centre (Irish: Ionad Ealaíon Halla an Línéadaigh), formerly Castlebar Town Hall (Irish: Halla an Bhaile Caisleán an Bharraigh), is a municipal building in Linenhall Street, Castlebar, County Mayo, Ireland.

[3] During close hand-to-hand fighting, between the attacking French forces, under the command of General Jean Humbert, and the forces defending the British garrison, under the command of General Gerard Lake, at the battle of Castlebar during the Irish Rebellion of 1798,[4] some shots damaged the doorcase of the building.

[5] After the battle Humbert used the building as a venue for a ball to celebrate his victory over the British forces and to rejoice at the proclamation of a short-lived provisional Irish Republic.

[6][7] The local linen trade died out in the first half of the 18th century and, in the wake Great Famine in the late 1840s, the people of the town were allowed to make use of the building.

[8][9][10] It then served as a meeting place for Castlebar Urban District Council until councillors decided to relocate to larger premises at Marsh House in Newtown Street in September 1979.
