14-20 Main Street, Randalstown, Antrim, Co Antrim

This is a two-story building situated in the main street of Randalstown, within a terrace. It dates from approximately 1840 to 1859, replacing an earlier building. A plaque on the wall indicates that a market house originally stood on this site, constructed in 1770 by Lord O’Neill. This earlier market house was destroyed by fire during the 1798 rebellion.

The building's exterior has been significantly altered. The ground floor now features a modern shop front flanked by modern panelled doorways, with the main entrance facing north. The roof is slated and has three chimneys – two made of modern red brick and one rendered. The first-floor wall is smooth cement rendered with rusticated quoins at the extremities. The windows on this level are modern rectangular timber fixed lights, set in square surrounds with keystones and projecting painted cills. The shop front woodwork incorporates panelled piers all of which are modern replacements.

The original market house, built in 1770, was described as a plain, two-story building, 60 by 25 feet. It had three large, circular arched gateways with iron gates. It served as a location for manor courts, petty sessions, and was used as a stable for cavalry during the 1798 rebellion. An Ordnance Survey map from 1829 depicts this original market house, while a map from 1858 shows the current building in its place. The building now functions as a shop and is located within a conservation area.
