Garz Slavic fort was an ancient burgwall. The earthworks have an oval shape, are about 200 metres long and 140 metres wide. There is an entrance roughly in the middle of the western side. Towards the lake of Garzer See to the south the ramparts are lower.
The castle was mentioned in 1165 as Borgar Gardz, when there were small-scale skirmishes with Danish warriors in front of the castle. The castle itself does not appear to have come under attack, but gradually fell into ruins afterwards. In 1300, the Prince of Rügen, Vitslav III, built a new castle and a chapel inside the original fort. After his death in 1325, the castle finally fell into disrepair. On the ramparts is now a war memorial to those who fell in the First World War and, in its immediate vicinity, is the Ernst Moritz Arndt Museum, where one can learn more about the history of the place.
The Garz fort is now a protected archaeological site. It ranks, in terms of size and degree of preservation, as one of the most important Slavic strongholds.References:
The Basilica of Santa Maria in Trastevere is one of the oldest churches of Rome. The basic floor plan and wall structure of the church date back to the 340s, and much of the structure to 1140-43. The first sanctuary was built in 221 and 227 by Pope Callixtus I and later completed by Pope Julius I.
The inscription on the episcopal throne states that this is the first church in Rome dedicated to Mary, mother of Jesus, although some claim that privilege belongs to the Basilica di Santa Maria Maggiore. A Christian house-church was founded here about 220 by Pope Saint Callixtus I (217-222) on the site of the Taberna meritoria, a refuge for retired soldiers. The area was made available for Christian use by Emperor Alexander Severus when he settled a dispute between the Christians and tavern-keepers.
The church underwent two restorations in the fifth and eighth centuries and in 1140-43 it was re-erected on its old foundations under Pope Innocent II.
