Børsen (The Stock Exchange) was built by Christian IV in 1619–1640 and is the oldest stock exchange in Denmark. It is particularly known for its Dragon Spire shaped as the tails of fourdragons twined together, reaching a height of 56 metres.
Christian IV had ambitions to turn Copenhagen into a metropolis and to strengthen the city's position as a commercial centre, he wanted a stock exchange along with the new merchant town Christianshavn he was constructing on the other side of the harbour. He asked Lorentz and Hans van Steenwinckel the Younger to design a building in Dutch renaissance with 40 small stalls at the ground floor and one big room at the upper floor.
The building was restored by Nicolai Eigtved in 1745 and internally renovated in 1855. It housed the Danish stock-market until 1974. In 1918, unemployed anarchists attacked Børsen, an attack that went to the Danish history books as 'stormen på Børsen' (the storm at the stock exchange).
References:The Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
