The Royal Palace of Milan (Palazzo Reale di Milano) was the seat of government of the city for centuries. Today it serves as a cultural centre and home to expositions and exhibitions.
Originally designed with a structure of two courtyards, the palace was then partially demolished to make room for the Duomo. The palace is located to the right of the facade of the cathedral opposite the Galleria Vittorio Emanuele II. The facade of the building follows the style of the ancient courtyard, forming a recess in respect to Piazza del Duomo, known as the Piazzetta Reale.
The magnificent Hall of Caryatids can be found on the main floor of the building. It occupies the site of the old theatre, which burned down in 1776 and is the only room that survived the heavy bombings of 1943. The damage caused by the incendiary and violent air movement was followed by a state of abandonment for over two years, which contributed to further serious damage to the building. Many of the neoclassical interiors of the Palace were lost.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.
