St. Eunan's Cathedral, also known as Raphoe Cathedral, is one of two cathedral churches in the United Dioceses of Derry and Raphoe in the Church of Ireland. Located in Raphoe, County Donegal, it is dedicated to Saint Eunan, who was the abbot of Iona in the 7th century. The cathedral has a complex history, with the oldest part dating back to the 12th century, and subsequent rebuilding and alterations from the 17th to late 19th centuries. The virtual re-building in the 17th century, directed by Bishop George Montgomery, played a significant role in its development. After restoration efforts in the 1890s, funded by the Knox family, the cathedral features a long narrow form, stained glass, and a decorative western doorway.
Medieval features, including a bishop's seat, shamrock-topped columns, and a piscina, are still present. Nearby remnants include a consistorial court building and a bishop's palace.
The Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
