Dunsoghly Castle
A couple of kilometres from Rivermeade, in the townland of Dunsoghly, stands one of the best-kept secrets in north Dublin. Dunsoghly Castle is a four-storey tower house built around 1450 for Sir Thomas Plunkett, Chief Justice of the Irish Common Pleas, with tapering square turrets at each corner. It is one of the very few fifteenth-century Irish tower houses to survive completely intact, and its arch-braced oak roof - four principals, still in place - is the only original medieval roof left standing in the country. It was used as the model for the roof restorations at Bunratty Castle and Rothe House. The Plunkets held it until the 1870s. Beside it is a small chapel carved with the Instruments of the Passion and dated 1573. The castle has been in State care since 1914 and is an OPW National Monument; the grounds stood in for Robert the Bruce's Edinburgh in the 1995 film Braveheart. Access is by the field gate and the tower itself is usually locked, so manage expectations - but the building, seen from the lane, is the real thing.
