Millennium Court Arts Centre houses two purpose-built gallery spaces and has been described as one of Northern Ireland’s premiere art spaces. MCAC is a young, fresh and experimental arts centre focusing on contemporary visual and verbal arts. MCAC's principle funders are Armagh City, Banbridge and Craigavon Borough Council and the Arts Council of Northern Ireland (Lottery Funding). 

The Centre also comprises a verbal art space, AV facilities that are networked throughout the building, a workshop area, darkroom, a kiln, and an artist-in-residence studio, all of which combine to create a vibrant and unique environment in which to cultivate and enhance the cultural environment of the community. The arts centre is located within Portadown's former municipal market hall, a converted red-brick building built in 1929.
