Ardtole was formerly the Parish Church of Ardglass and is dedicated to St Nicholas, the patron saint of sailors. The structure is of a characteristic Anglo-Irish parish church of the Middle Ages. The long narrow church seems largely of 15th century date, with a huge east window and opposed north and south doors, one with a draw-bar hole. In 1791 a cross-decorated slab of the Early Christian period was found, showing that perhaps the site has a longer tradition than the surviving remains would suggest. A souterrain was also found south of the church. The early cross slab, now built into the Roman Catholic church at Chapeltown, and the souterrain, suggest Early Christian activity on the hilltop.
The Church sat halfway between the Anglo-Norman settlers and traders of Ardglass and the native Irish of the surrounding area, but was used by both sets of people until the 15th or 16th century. According to tradition some people from Ardglass found the chieftain of the MacCartans in a drunken sleep and fastened his hair to some briars. He avenged this affront with a massacre of the townsmen gathered together for mass in Ardtole Church. This disaster led to the abandonment of the building as a place of worship for Ardglass, probably in the 16th century.
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.
