Hedrum Church was built of stone around 1100 and has 260 seats. The church has a rectangular nave, square choir and apse. Archaeological excavations show that the apse is added later. The structure was extended by four meters in 1666. The west part with the portal and door openings are from after the Reformation. Hedrum Church has a number of tombstones, which cover large parts of the floor of the church. Hedrum Church cemetery is clearly visible from traffic arteries on both sides of Numedalslågen. Some of the graves are believed to pre-date the introduction of Christianity confirming the supposition that ancient pagan cult sites were chosen as the venue for the earlier churches.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.
