The Mussenden Temple lies within the grounds of Downhill Demense and is located in one of the most amazing coastal locations in the world, perched literally at the edge of a cliff which falls away to the rocks and beach far below. The Mussenden Temple was originally built as a library, and the inscription on the outside of the temple reads, “Suave, mari magno turbantibus aequora ventis e tarra magnum alterius spectare laborem” which translates to “Tis pleasant, safely to behold from the shore, the troubled sailor, and hear the tempests roar.”

It is one thing to have both the leisure time and a good book, but the Earl Bishop, who built it, tops them all when it comes to creating a magnificent building with such a great view to house his books. What an amazing location for a library! The Temple itself is only open to the public at certain times.
