The Forum of Augustus is one of the Imperial forums of Rome, Italy, built by Augustus. It was built in 42 BC to commemorate Augustus' victory at the Battle of Philippi over the assassins of Julius Caesar.
The Temple of Mars Ultor stands in the forum. It was inaugurated in 2 BC and it came to function as the focal point of Roman military strategy. For example, Augustus decreed that it should be the meeting place for the Senate when decisions of war were taken. The temple was also the place where young Roman males were ceremoniously given their adult toga, thus becoming eligible for military service, and it was the official departure point for commanders embarking on military service in the empire.
Behind the temple stands a 30 m high tufa wall which is topped with white travertine. It was constructed to separate the Forum from the hill residences behind it and to act as a firewall should a fire start in this densely-populated area of the city. In the 1st century AD Tiberius added two arches to the temple sides in honour of his two sons Drusus the Younger and Germanicus but these have now been lost except for the foundations of one. In the 2nd century Hadrian repaired parts of the building but from the 5th century the building went into decline and blocks began to be re-used in other building projects.
From the 12th century soil was added to the site and the area used for agriculture, however, as the drains were then blocked, a marsh formed until the area was drained in the 16th century.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
