Rinn Duin and Local history

St John’s House is an ideal location for those interested in heritage and archaeology.

We are situated in the historic Rinn Duin peninsula, a site of national importance, which has the best preserved deserted Norman town in Ireland including a 550 metre town wall with three towers and a gatehouse, windmill, Norman parish church and a fratres cruciferi hospital which are undergoing stabilisation by the Heritage Council, DoE and Roscommon County Council. There are heritage information boards at all of these sites.

The only Bee bole (18th century beehive alcoves) in County Roscommon and one of only 44 in Ireland is located behind the house.


Rinn Duin walk

Within a few kilometers there is a wealth of largely undisturbed archaeology including multivallate ringforts, medieval windmills, megalithic tombs, barrows and standing stones. Roscommon has an excellent Royal Norman castle and Abbey. Athlone castle is only a short trip away.

The world famous Clonmacnoise monastery is only 30 minutes away by car, as is Rathcroghan, the complex of over 50 prehistoric archaeological sites near Tulsk.

A guided tour of Rinn Duin or nearby sites can be arranged. Quaker Island, in Lough Ree, is a wonderful visit with its wealth of medieval churches.
