The Macellum of Naples was the macellum or market building of the Roman city of Neapolis, now known as Naples. Due to the rise of the ground level the macellum is now located beneath the church of San Lorenzo Maggiore. The first construction dates to 5th or 4th century BC when the area was the location of the agora during the Greek period. When Neapolis became a Roman possession it was eventually transformed into a macellum. This structure was covered by a mudslide in the 5th century AD, probably as a result of flooding.
An early Christian basilica was constructed over the remains of the covered macellum. Consequently, this basilica was replaced by new construction over the centuries. As a result, the mud slide preserved the remains of the macellum,
The macellum had an entrance to the north, where the Via dei Tribunali runs now. The rectangular building consists of a porticoed area with workshops and an internal open courtyard with mosaic floors. In the middle of the courtyard was a tholos, a circular building used for food selling. Small tabernae, a laundry and the treasury can still be recognized.
Today the macellum can be visited as a part of the monumental complex of San Lorenzo Maggiore.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.
