[1] The East Bridge Street site had previously been occupied by a gaol which had been built on the initiative of a Captain Cole who secured permission to proceed with the development in May 1613.

[2] The design also involved a sessions house which was built on piers over the gaol which was itself constructed in a vault below ground.

[3] The new design involved a symmetrical main frontage with five bays facing onto East Bridge Street; there were square sash windows on the ground floor, rounded headed sash windows on the first floor and a cornice decorated with modillions at roof level: the central section featured a prominent single-storey portico with four Doric order columns supporting a heavy entablature.

[9][10] The courthouse continued to operate as a venue for administering justice until it closed in 1969; however, following a major restoration, it re-opened again on 11 September 1982.

[11] In May 2012 the justice minister, David Ford, said that he accepted an inspection report recommending that the Enniskillen Courthouse should be designated a "satellite court" in a proposed rationalisation of the court system.
