[2] During the Irish Civil War, the building became the headquarters of the pro-treaty forces commanded by Brigadier-General Joe Ring in July 1922.

The troops billeted there shot off the head of the statue of the banker, George Clendining, in the middle of The Octagon, during their defence of the town.

[3] After the war, the town hall continued to serve as a venue for public events, such as a performance of the comic opera, The Mikado, produced by the Westport Musical Society in May 1938.

[4] In 1966, on the 50th anniversary of the Easter Rising, the Minister for Social Welfare, Kevin Boland, visited Westport and inspected a guard of honour outside the town hall.

After completion of the works, which cost €3.2 million and were financed by Department of Arts, Heritage and the Gaeltacht, Mayo County Council, the South West Mayo Development Company and Fáilte Ireland, the building was officially re-opened by the Minister of State for Tourism and Sport, Michael Ring, in June 2015.
