Poskær Stenhus is Denmark's largest round barrow, dating from the age of Funnelbeaker culture (around 3300 BC). The best view of this monument is from the north approach by the road through the hills of Mols Bjerge. The burial chamber has a diameter of more than 2 metres and a ceiling height of almost 1.8 metres. The chamber is surrounded by 23 kerb stones, some of which are more than 2.5 metres high. In 1859, the owner, Ole Hansen, started blasting the barrow stones to sell them as building material. He needed the money for his family and couldn't turn a proper living from the land where the barrow was. The barrow was rescued by local officials.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.
