Liebfrauenkapelle, oldest church in Zug, was built in the 13th century at the same time as the first city walls. From the outside, the Liebfrauenkapelle was a bulwark forming part of the edge of the city, with a somewhat surprising delicately decorated interior, showing aspects of both the Late Gothic period, with its murals, and the Baroque period, with the scenes depicting the life of the Virgin Mary. This old chapel in the middle of the Old Town has a particular atmosphere of its own, which is why it is very popular place to get married.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.
