The Orthodox church of Tampere was built in Russian romantic style, with onion style cupolas, and was completed in 1899. The architect of the Russian army, T.U. Jasikov, drew the floor plan. The church was consecrated in 1899 to Saint Alexander Nevsky, a Novgorodian who in 1240 fought against the Catholic Swedes and two years later the Catholic Teutonic Knights with equal success, and was accordingly canoniced for these nationalistic but bloody deeds. Emperor Nicholas II donated the bells to this church. The church suffered heavily during the Finnish civil war in 1918 and most of the movables were disappeared or destroyed. The reconstruction took several years. After Finland declared its independence, it was re-consecrated to St. Nicholas, a less belligerent saint.
The Orthodox Church is considered to be one of the most beautiful buildings in Tampere. Indeed, it is even said that it is the finest masterpiece of Byzantine-style architecture in the Nordic countries.

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.
