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:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
