Castles

Sketrick Castle lies on Sketrick Island in Strangford Lough, south east of the town of Comber, in County Down, in Northern Ireland.
Local tradition has it that Sketrick Castle was built by the Vikings but an Anglo-Norman or even 15th century origin is more likely. During the 16th century it was several times actively involved in warfare.
After centuries, in 1957 a small, stone, subterranean passage was discovered. It has lintels running eastwards under the bawn wall to a space with a corbel over a fresh water spring. The passage is less than 1 meter high and about 15 meters long.
The tower house is like us in some ways, as we also hide deep secrets or strengths beneath the surface. So be careful in passing judgements based only on what you see.
