Llandovery Castle is a late thirteenth-century ruin which occupies a knoll overlooking the River Towy and the land surrounding it. The Normans built a castle in the current location in the early twelfth century and this was rebuilt in stone. It was burnt in the early sixteenth century and never repaired.
A Norman knight, Richard Fitz Pons, received the lordship of Cantref Bychan in 1116 and he probably began construction of a motte-and-bailey castle in same year. It was repeatedly lost to the Princes of Deheubarth over the next several generations. King Henry II of England spent a great deal of money repairing the castle in 1159–62, but the Welsh captured it regardless. It finally fell to the English under Edward I in 1277. It was briefly retaken by Welsh forces under Llywelyn ap Gruffudd five years later. The castle was then granted to John Giffard, 1st Baron Giffard, who likely rebuilt it in stone. The building passed to the baronial Audley family of Heleigh in 1299 (who later inherited the lordship of Cemaes in north Pembrokeshire) and then into the Touchet family in the fourteenth century. King Henry IV of England visited the castle in 1400 and it was besieged during the Owain Glyndŵr rebellion three years later. The castle was burnt in a rebellion led by Hywel ap Rhys in 1532 and was never rebuilt.
The keep is a large D-shaped tower on the western side of the castle. The gatehouse has two towers on the north side with a well-tower. There are also remnants of the curtain wall around the filled-in ditch.
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.
