Tongeren Béguinage, founded in 1257 is listed as a UNESCO World Heritage Site since 1998. Its enclosure wall was destroyed in the 19th century: it separated the beguinage from the rest of the city and thus guaranteed peace and quiet for the small religion-inspired community. In the 17th century the beguinage counted some 300 beguines; it was also able to survive the 1677 fire that destroyed most of the city. In the center of the béguinage stands the Saint Catherine Church, built in 1294 and one of the oldest churches in the entire city.
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.
