Büren Castle was built in 1621-24 as the residence of the Bernese Landvogt over the area. It was built on the site of four farm houses. Between 1624 and the 1798 French invasion a total of 77 Landvogts lived in the castle. Some of the bullet scars from the troops that invaded in 1798 are still visible on the castle walls. Today the castle is home to the municipal administration and government offices. In 2003 the 17th century murals and other art were restored to their original appearance.
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.
