The building accommodated the offices of Naas Town Council until 2014 but has subsequently been converted into a public library and cultural centre.

[3] The gaol was extensively used during the Battle of Naas, in which the town was defended from rebels led by Michael Reynolds during the Irish Rebellion of 1798.

[9] Then, on 15 April 1918 as part of the Irish anti-conscription movement of 1918, a demonstration was held outside the town hall to protest proposals by the Lloyd George government to introduce conscription in Ireland: attendees included the local member of parliament, John O'Connor.

[11] An extensive programme of refurbishment works, intended to allow the library service to relocate from Harbour View, commenced on site in November 2020.

[12][13] The works, which created a new cultural centre as well as a new library, were undertaken by Duggan Lynch at a cost of €5.9 million to a design by Deaton Lysaght Architects, and were substantially complete by late 2023.
