A small round clifftop temple perched on the very edge above Downhill Strand, with the romantic ruins of a great house and its walled garden behind it — said to be one of the most photographed spots in Ireland.
What you'll see — Mussenden Temple standing alone on the cliff 120 feet above the Atlantic, the roofless shell of Downhill House (the Bishop's Palace) you can wander freely, the restored walled garden, and huge views over Downhill Strand west to Magilligan and the hills of Donegal.
How long & who for — an easy 1–2 hours for the temple and house, half a day to walk the whole estate. Open grassland and coastal air suit all ages, and dogs are welcome on leads.
Cost & parking — a National Trust site: walking the grounds is free, open dawn to dusk all year. Parking is £10 a vehicle, card only — free for Trust members and Blue Badge holders.
What to bring — a windproof coat (it's a very exposed clifftop and often gloriously blowy), sturdy walking shoes for grass and uneven ground, and a card for parking. Al's Coffee Hut sits at the Lion's Gate, roughly 10am–5pm.
Mind the cliff edge. The ground out by the temple is open and unfenced in places, 120 feet above the sea — keep a close eye on children up here.
The temple interior opens only occasionally. Inside is used for events, weddings and the odd guided tour, so most days you're admiring Mussenden from the outside.
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 what's often called one of the most photographed sights on the whole north coast.
