You walk out across open grassland with the sky wide above you, past the bones of Downhill House — a great roofless ruin you can wander freely through, its empty windows framing the light. Keep going toward the edge, and then it appears: Mussenden Temple, a perfect round little library standing alone against the sky on the very lip of the cliff, with nothing beyond it but ocean.
It sits 120 feet above the Atlantic, and the view from up there is the whole point. Seven miles of Downhill Strand curve away below, the surf rolling in white. Look west and the coast runs on to Magilligan Point, and past it the hills of Donegal rise blue in the distance. On a bright blowy day up here — and it often is blowy, gloriously so — the wind comes straight off the sea and the whole place feels alive.
It's a spot that rewards a wander. You can circle the temple, peer out over the strand, poke around the shell of the old house, and just stand and take in one of the finest coastal outlooks anywhere in the north. Bring a coat, follow the grass to the edge, and let the Atlantic do the rest.
Plan your visit
Can I visit? Yes — the grounds are free, dawn to dusk.
This is a National Trust site, and walking the grounds costs nothing — you're free to roam the demesne, explore the Downhill House ruin and get right out to the temple on the cliff edge, every day of the year from first light to last. The facilities at the Lion's Gate run seasonally, roughly 10am to 5pm, so if you're counting on the coffee hut or the toilets, check the hours before a specific trip.

Two to remember:
Parking is £10 per vehicle and the pay-and-display is card only — free for National Trust members and Blue Badge holders. And the temple's interior only opens for events, weddings and occasional guided tours, so on most days you're admiring it from the outside.

Getting there
Mussenden Road, Castlerock, County Londonderry, BT51 4RP — just above Downhill on the coast road, with pay-and-display parking on site.
The temple was built in the 1780s for Frederick Hervey, the Earl-Bishop of Derry — a wealthy, well-travelled churchman who set his grand house, Downhill, on this windswept headland and dotted its grounds with follies.
The temple is said to have been modelled on the Temple of Vesta in Italy, and is named for his cousin, Mrs Mussenden. Built as a library and reading room right on the cliff edge, it has weathered more than two centuries of Atlantic gales to become one of the most photographed sights on the whole north coast.
