This historic 12th century building is a typical example of an Anglo-Norman motte with a kidney-shaped bailey. The 7.6m high mound, which once housed a wooden tower, was later replaced by a stone tower house, the ruins of which can still be seen today. Access is via Clough's main road; there is a small car park, but it is not always well signposted. Access is usually permitted. The surrounding countryside, with views of the Mourne Mountains, offers a tranquil atmosphere that invites you to linger.

The motte and bailey dates to c.1200 and is an excellent example of an Anglo-Norman earthwork castle. The taller mound, the motte, was built of earth to provide a look-out position and the central defence. Excavations at the top of the motte during the 1950s uncovered a wooden palisade which originally extended around the summit. When you climb the motte you realise what an important position the castle is in, over looking the routes east to Downpatrick, south to Dundrum and north to Belfast Lough. The views from the top of the motte west to Slieve Croob are particularly fine.

The beautiful Dundrum Castle is located on a hilltop near Dundrum village. Its elevated position provides fantastic panoramic views across Dundrum, the Carrigs Estuary, the Mourne Mountain range and out to the Irish Sea. The castle itself was constructed by John de Courcy at the beginning of the 13th century. It's a fine example of a historic medieval castle of its time.

This extraordinary castle sits in Castlewellan Forest Park and has a grand view over the lake. From the walking and cycle trail around the lakeside, you can enjoy the fantastic vantage point and admire the castle's turrets. Built in the mid 1800s, the castle was owned by the Annesley family. Its grounds contain a phenomenal arboretum which has been considerably extended and includes giant sequoias. The building is now a Christian conference centre and isn't open to the public. It's well worth seeing from the outside though, and the lawns around the lake are a perfect place for a picnic.

Lovely looking castle surrounded by a lake and lots of trails for walking and cycling. Unfortunately, the castle is not open to the public and swimming is not allowed in the lake (fishing and boats are fine).
