Clonca Church & Cross is one of the most important and popular historical sites in Inishowen. The 17th century church ruin at Clonca is believed to have been built on the foundation of an earlier church associated with a monastic site founded by St Morialagh in the 6th century. The monastery was one of the most important foundations in the development of Christianity on Inishowen. It's proximity to Carrowmore and another monastic site founded by St Boudan in Culdaff made this area a great seat of skill and learning. Only two high crosses remain - an upright tall cross and the head of another cross lying prostrate with a large base next to it.
Standing inside the church are two carved grave slabs. Although the stone on the left, see below, is quite modern in comparison to the early grave slab, it is never the less, a very interesting slab. An inscription in Lombardic lettering reads ' magnvsma corristin iaeotkiseo' translated as MAGNUS MACORRISTIN OF THE ISLES... MacGorristan is believed to have been a scotsman and there are several stories as to how this grave slab ended up at Clonca in Donegal. The beautifully carved slab bears a shinty stick and ball. Shinty is a game, very similar to hurling, played in Scotland.
References:Dryburgh Abbey on the banks of the River Tweed in the Scottish Borders was founded in 1150 in an agreement between Hugh de Morville, Constable of Scotland, and the Premonstratensian canons regular from Alnwick Abbey in Northumberland. The arrival of the canons along with their first abbot, Roger, took place in 1152.
It was burned by English troops in 1322, after which it was restored only to be again burned by Richard II in 1385, but it flourished in the fifteenth century. It was finally destroyed in 1544, briefly surviving until the Scottish Reformation, when it was given to the Earl of Mar by James VI of Scotland. It is now a designated scheduled monument and the surrounding landscape is included in the Inventory of Gardens and Designed Landscapes in Scotland.
David Erskine, 11th Earl of Buchan bought the land in 1786. Sir Walter Scott and Douglas Haig are buried in its grounds.
