Edin's Hall Broch is a 2nd-century broch near Duns in the Borders of Scotland. It is one of the most southerly broch survivals, which are more typically associated with Northern Scotland.
The broch stands in the northwest corner an Iron Age hillfort which presumably pre-dates the broch. The hillfort consists of a double rampart and ditches, enclosing an oval area some 135 metres by 75 metres. A large circular structure (roundhouse) in the centre of the fort, close to the broch, may have been the most important building before the broch's construction.
It is assumed that the hillfort dates to the pre-Roman Iron Age. The date of the broch is uncertain but it has been speculated that it was built between the two main periods of Roman occupation in Scotland: some time in the 2nd century AD. Excavations at Torwoodlee Broch, also in the Scottish Borders, has shown that it was built and demolished during this period.
Within the hillfort is an array of stone footings marking the positions of houses and other structures. Some of the houses overlie the defences – indicating that they are later than hillfort and may be later than the broch as well.
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.
