The parish church of Saint Tanwg at Llandanwg is situated just behind the beach in the sand dunes just 20 metres above the high tide mark. The church is medieval, probably dating from the 13th century, however there are three 5th to 6th century inscribed stones and two stones with inscribed crosses inside the building which indicates much earlier activity. It has probably been a place of worship since the Age of the Saints, possibly as early as the first part of the 5th century. Much of the churchyard is buried in sand. The churchyard contains the war graves of a Royal Welsh Fusiliers soldier and Royal Garrison Artillery officer of World War I.
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.
