Mussenden Temple sits right on the edge of a 120ft cliff above Downhill Beach, near Castlerock in Co. Londonderry, with views across to Donegal and the Atlantic. It’s one of the most photographed buildings on the north coast, and the centrepiece of the wider Downhill Demesne, now cared for by the National Trust.
Why it’s here
The Temple was built in 1785 by Frederick Hervey, the Church of Ireland Bishop of Derry (and, from 1779, 4th Earl of Bristol) — a wealthy, eccentric figure known for building grand houses across his estates. He used it as a private library, and it doubles as a memorial to his cousin Frideswide Mussenden, who died in 1785 at just 22.
The design is thought to be based on the Temple of Vesta at Tivoli, near Rome, most likely by way of Bramante’s Tempietto — an architectural reference Hervey would have seen on his travels in Italy. The inscription running around the building is a line from the Roman poet Lucretius, translating roughly as “Tis pleasant, safely to behold from shore the troubled sailor, and hear the tempests roar.”
Hervey was also one of the first people to study the Giant’s Causeway as a volcanic geological formation and brought it to the attention of the Royal Society — an early step in turning it into the attraction it is today.
Downhill House
The main house was built from 1775, restored after a serious fire in 1851 destroyed much of its art collection and library, and restored again between 1870 and 1874. It was used to billet RAF personnel during the Second World War, then sold off and largely dismantled by 1950. Today it’s a roofless ruin — atmospheric to walk through, but a shell rather than an interior. The Temple itself has fared much better, though for years it was at real risk from cliff erosion; the National Trust carried out stabilisation work in 1997 to secure it.
Around the grounds
Beyond the Temple and the ruined house, the wider demesne is worth the walk: the Black Glen (a small sheltered arboretum), the Walled Garden, the Bishop’s Gate entrance with its carved bishop’s mitre and cow skulls, and the Mausoleum, a cenotaph built for Hervey’s brother George.
On screen
Downhill Beach below the Temple appeared as Dragonstone in Game of Thrones Season 2 — the scene where Stannis Baratheon and Melisandre burn effigies on the sand was filmed here, with the Temple providing a striking backdrop. See the full list of Causeway Coast filming locations for more.
Getting there
By car from Portrush, it’s about 25 minutes via Coleraine, following signs for Castlerock — or take the coast road (A2) through Portstewart for a slower, scenic route. By public transport, take the bus or train to Coleraine, then a connecting bus toward Limavady; the Belfast–Derry train also stops at Castlerock, about a 2km walk, taxi, or short bus ride from the Temple itself.
