St Cynfelin (also known as St Matu) is reputed to be the founder of St Mary's Church in Welshpool, during 'the age of the saints in Wales' in the 5th and 6th centuries.
The church was originally built c. 1250, but only the lower courses of the tower now remain from that date. The current building is largely as rebuilt or restored in 1871 by George Edmund Street. The nave was rebuilt in the 16th century, and with the whole building was substantially restored in 1871.
The 15th century chancel ceiling may have come from Strata Marcella Abbey, about five miles away, and a stone in the churchyard is said to have been part of the abbot's throne. A memorial in the church commemorates Bishop William Morgan, translator of the Bible into Welsh, who was the vicar from 1575 to 1579.
The churchyard contains seven Commonwealth war graves, of five British soldiers of World War I and a soldier and airman of World War II.
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.
