Historically there has been a deep water harbour in use at Ardglass for around 3,000 years. In the 15th Century Ardglass was Ulster’s busiest medieval port.
The origins of the modern harbour that you see today happened in 1812 when the first pier was built to shelter ships from the weather. During Victorian times it was developed as the fishing industry grew and is now the home to around 30 fishing boats.
Ardglass originates from the Irish ‘Ard Ghlais’, meaning ‘green height’ and is one of Northern Ireland’s most historical towns, boasting more medieval tower houses than any other town in Ireland.
