Penmon’s history stretches back to the 6th century, when a monastery was established here by St Seiriol. The holy well (with reputed healing properties) that bears his name is thought to be associated with this period, though the ‘cell’ that houses it is a much later construction. The remains of the priory that stand today largely date from the 13th century, when it became part of the Augustinian order.
Inside the church, which still serves the parish today, stands an impressive cross. Dating from the 10th century, its shaft is carved with intricate patterns of frets and plaits.
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.
