The parade formed up outside the Royal British Legion in Thomas Street, where sprigs of shamrock were presented to those on parade.
A short service was held, after which the parade made its way through the town accompanied by St Mark’s Band.
The Lord Mayor of Armagh City, Banbridge and Craigavon Borough, Alderman Stephen Moutray, and a number of dignitaries presented a sprig of shamrock to the veterans on parade.
Afterwards there was an afternoon of celebration with traditional St Patrick’s Day food and entertainment in the Legion function rooms.
