The Broch of Borwick is an Iron Age living structure. It has an external diameter of 17 metres and an internal diameter of 8 metres. The walls which are 3.5 to 5 metres thick currently stand to a maximum height of 2.6 metres. The eastern half of the broch and the entrance passage are well preserved, but the western half has been destroyed by erosion. The entrance passage, which is still lintelled over, is 5.6 metres long with door-checks each formed of a slab set on edge 3 metres from the outside. A guard cell opened off the right of the passage.
The broch was once cut off from the flat land beyond by an outer wall, and there were outbuildings between the wall and the broch.
The site was excavated in 1881 by W. G. T. Watt, and the interior was cleared of debris. Ashes, bones and shells mixed with clay were found under the rubble. Beneath this was a layer of small flat stones and under this the broch floor. Finds included several combs, a small whale vertebra cup, a spindle whorl, a stone gaming piece, a whetstone, hammerstones, some stone knives and choppers, an iron rod, and some querns.
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.
