Lisnagade is a large multivallate earthen ringfort, three miles west of Banbridge. It is an impressive circular earthwork, consisting of three massive ditch-separated banks, approximately 6m high, which completely surround the fort. The diameter of the inner circle is a good 60m and the total diameter of the rath is about 110m. There is a smaller rath annexed to the north by two straight ditches. This rath is very low and is about 30m diameter. It is surrounded by a single ditch.
Though bronze artefacts have been recovered from the site, little is known about its occupants. This ancient site dates back more than 1000 years, and is thought to have been constructed around 350 AD. The interior has now only low undergrowth and a beech tree just off centre. The banks are planted with a variety of well established trees as well as small bushes.
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.
