About
There cannot be a wilder and more dramatic headland in Northern Ireland than Downhill Estate. With fabulous views that stretch over the whole of the North Coast of Ireland and open windswept cliff top walks, it is not surprising that the estate is part of the Binevenagh Area of Outstanding Natural Beauty and a signature walking experience.
Setting off from Castlerock train station, the 4.2mile circular walk offers a wild and rugged headland with fabulous clifftop walk before arriving at Downhill Estate to explore its collection of intimate gardens, ruins and iconic temple.
Your 2 hours walk takes in Mussenden Temple, located in the beautiful surroundings of Downhill Demesne. It perches dramatically on a 300ft cliff top, high above the Atlantic Ocean on the north-western coast of Northern Ireland, offering spectacular views westwards over Downhill Strand, towards Magilligan Point and County Donegal and to the east Castlerock beach towards Portstewart, Portrush and Fair Head.
The temple was built in 1785 and forms part of the estate of Frederick Augustus Hervey, Bishop of Derry and Earl of Bristol (or the Earl Bishop). The temple was built as a summer library and its architecture was inspired by the Temple of Vesta in Tivoli, near Rome. It is dedicated to the memory of Hervey's cousin Frideswide Mussenden and uniquely reflects the personality of its flamboyant creator.
Both the Temple and the breathtaking views are among the most photographed scenes in Ireland.
