Opposite the children's play park you can see the Georgian Bathing House, built during Ardglass' hay day as a spa and bathing centre. It afforded ladies privacy to change before going for a swim.
This small tower is reminiscent of the type of garden follies which were fashionable in Georgian estates. Originally there was a sea wall which retained the tidal waters for bathers. It was sympathetically restored in 2015 by The Follies Trust.
The bathing house is located in a part of Ardglass known as Luke's Port. During the Middle Ages this port was an important berth. Here bishops would disembark to attend the ecclesiastical court which was located in the church at the top of the Greenhill Steps.
