During the centuries of German economic domination, the guilds were Riga's power brokers. The former, dating from 1384, was the home of the merchants, while the latter held the city's artisans. These slightly different audiences are reflected in the respective usage of the buildings today: while the Great Guild is home to the Latvian Symphony Orchestra, its smaller cousin hosts conferences and the occasional disco. The Small Guild is now also open to the public during the day for a small admission fee of 1Ls.
References:Kristiansten Fortress was built to protect the city against attack from the east. Construction was finished in 1685. General Johan Caspar von Cicignon, who was chief inspector of kuks fortifications, was responsible for the new town plan of Trondheim after the great fire of 18 April 1681. He also made the plans for the construction of Kristiansten Fortress.
The fortress was built during the period from 1682 to 1684 and strengthened to a complete defence fortification in 1691 by building an advanced post Kristiandsands bastion in the east and in 1695 with the now vanished Møllenberg skanse by the river Nidelven. These fortifications were encircled by a continuous palisade and thereby connected to the fortified city. In 1750 the fortress was modernized with new bastions and casemates to protect against mortar artillery.
