Paphos (Pafos) Castle was originally a Byzantine fort built to protect the harbour. It was rebuilt by the Lusignans in the 13th century, dismantled by the Venetians in 1570 during the Ottoman invasion and rebuilt by the Ottomans after they captured the island in the 16th century. Originally, this role was served by the Saranta Kolones fort, the ruins of which lie a few hundred meters to the north.
During its long history, the Pafos Castle was used, as well as for protection, as prison cells, and even as a storage area for salt when the island was a British colony. In 1935 it was declared an ancient monument and today is considered as one of the hallmarks of the Pafos region.
Many cultural events take place in the square just in front of the castle, while during September each year the Pafos Aphrodite Festival which presents a different opera every year staged here by world famous artists with the castle building usually acting as part of the scenery.
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.
