[6] A Carnegie library, which was designed by Sinclair MacDonald in the neoclassical style, was erected just to the south of the town hall in 1910.

[9] Other visitors included the Queen Elizabeth II, accompanied by the Duke of Edinburgh, who arrived at the town hall in June 1964.

[11] A public inquiry was held in the town hall, to consider government proposals to build a European Demonstration Fast Nuclear Reprocessing Plant at Dounreay, in 1986.

[15] In order to accommodate this, an expanded museum complex, comprising the Carnegie library building and the town hall, was established at a cost of £3.5 million,[16] and was officially re-opened by Duke of Rothesay as "Caithness Horizons" on 3 August 2009.

[19] After a further refurbishment and a change of management, the museum was rebranded as the "North Coast Visitor Centre" and re-opened again in November 2021.
