It is a voluntary, not-for-profit organisation, placing commemorative plaques in public places in honour of people and locations that have contributed to all genres of history within the boundaries of the nine-county province of Ulster. Founded in the early 1980s, the group receives no government funding, unlike many similar organisations in the United Kingdom.
