Fredriksvern or Stavern has probably been a harbor since ancient times. The name is found in written sources the 11th century and in the 12th century it is referred to as a good fishing harbor. The military activities in Stavern began with building of Staverns Fortress, part of a major construction of Norwegian Fortresses which took place from 1675 to 1679 under Christian IV. Citadellet Fort was built in the 1680s by count Fredrik Gyldenløve and had an important role during the last Nordic war from 1709 to 1720.
During the winter of 1748-1749 Fredrik V ordered construction of a shipyard and a drydock in Norway and in 1750 the first Norwegian naval command base was constructed. The king did so as a defensive measure in the event of a war with Sweden. A naval station in Norway could support land strength in the event of a Swedish invasion by cutting off naval transport of Swedish troops and supplies, reducing the risk of such an invasion. Fredriksværns Værft (the shipyard) was finished in 1750 and a number of vessels were built there, including a frigate in 1775. Fredriksvern Church was finished in 1756 as the garrison church in a style with influences from both Renaissance and Baroque.
The main base for the Common Fleet was at Copenhagen, but when Norway and Denmark split in 1814 Fredriksvern became the main base for the Royal Norwegian Navy. The Common fleet had been decimated by the British robbery in 1807 and the Norwegians got the lesser share of what was left when the union was ended. It soon became apparent that major expansion of the navy had to take place. Fredriksvern had one strategic flaw, it was difficult to defend from a land based attack. In addition its capacity was too small for the new expanded navy. Already in 1815 it was decided to look for a new location for the main naval base. But Norway was extremely poor and both the fleet expansion and the building of the new base was delayed. During the 1830s a new main naval base was constructed at Horten, but Fredriksvern continued to be an important naval base and remained active as an air force academy until 2002.References:
The Arch of Constantine is situated between the Colosseum and the Palatine Hill. It was erected by the Roman Senate to commemorate Constantine I's victory over Maxentius at the Battle of Milvian Bridge in 312. Dedicated in 315, it is the largest Roman triumphal arch. The arch spans the Via triumphalis, the way taken by the emperors when they entered the city in triumph.
Though dedicated to Constantine, much of the decorative material incorporated earlier work from the time of the emperors Trajan (98-117), Hadrian (117-138) and Marcus Aurelius (161-180), and is thus a collage. The last of the existing triumphal arches in Rome, it is also the only one to make extensive use of spolia, reusing several major reliefs from 2nd century imperial monuments, which give a striking and famous stylistic contrast to the sculpture newly created for the arch.
The arch is 21 m high, 25.9 m wide and 7.4 m deep. Above the archways is placed the attic, composed of brickwork reveted (faced) with marble. A staircase within the arch is entered from a door at some height from the ground, on the west side, facing the Palatine Hill. The general design with a main part structured by detached columns and an attic with the main inscription above is modelled after the example of the Arch of Septimius Severus on the Roman Forum.
