The Church of the Eremitani, or Church of the Hermits, is an Augustinian church of the 13th century. It was built in 1276 and dedicated to the saints Philip and James; it is however best known as degli Eremitani from the annexed old monastery, which now houses the municipal art gallery.
The chapel of SS. James and Christopher (Ovetari Chapel), formerly illustrated by Mantegna's frescoes, was largely destroyed by the Allies in World War II, because it was next to a German headquarters. There are more than 88000 fragments covering only 77 m2, while the original area covered several hundreds. Other artists whose frescoes are preserved in the church include Guariento and Ansuino da Forlì.
The church contains the tombs of Jacopo II da Carrara (d.1351) and Ubertino da Carrara (d.1345) da Carrara, lords of Padua, both by Andriolo de Santi (de Sanctis) and others. They were formerly in the church of Sant'Agostino, but were moved here after that church was razed in 1819.
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.
