The Albaicín retains the narrow winding streets of its Medieval Moorish past dating back to the Nasrid Kingdom of Granada. It was declared a World Heritage Site in 1984, along with the Alhambra. In the Albaicín there are numerous monuments from different periods, mainly the Nasrid period and the Renaissance.
The traditional type of house is the carmen, consisting of a freestanding house surrounded by a high wall that separates it from the street and including a small orchard or garden. The channeling and distribution of drinking water through pipes laid from wells was characteristic of this district; about 28 of these have been found, of which most are preserved but not in use because the pipes were broken over time.
In December 1499, the Albaicín was the starting point of a rebellion throughout Granada, triggered by the forced conversion of the Muslim population to Christianity.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.
