The present structure of Trinitatis Church was consecrated in 1690 and built in a late medieval style. A few decorated stones are included in the foundations, which come from a medieval church that was pulled down shortly after the setting up of Fredericia as a fortified town around 1650. The Romanesque font comes from the same source and along with a Baroque font canopy, is one of the church`s treasures. The majority of the interior is otherwise influenced by the late Baroque style. There are several memorials in the cemetery that are of significance for military historians.
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.
