The earliest documentary record of the church in Cilcain is in the Lincoln Taxation of 1291 although it is believed that its origin was in the medieval period. In the 15th century the south nave and tower were added. As a result of a fire in 1532 the north nave was burnt down and it remained without a roof until it was rebuilt in 1746. It is thought that at this time the ornate timber roof was added to the south nave. The tradition is that this came from Basingwerk Abbey but there is no evidence to support this. Also at this time a priest's door in the south wall was blocked and it is possible that a west gallery was constructed. In 1845–46 restoration work took place under the direction of Ambrose Poynter. A more substantial restoration was carried out by the Chester architect John Douglas between 1888 and 1889 which was paid for by William Barber Buddicom, a railway engineer.
The church is built in stone of a variety of types, with a slate roof. Some of the fabric from the 13th century church survives in the north nave. The plan consists of a double nave with a tower at the west end of the north nave, and a south porch. The tower has stepped diagonal buttresses at the west corners and a clasping buttress at the northeast angle. On its north wall is a door under a round-headed arch. The tower is surmounted by a battlemented parapet, a low pyramidal roof and a weathercock.
The roof of the south nave has alternating arch-braced and hammerbeam trusses. It is decorated with angels, shields, grotesques and other secular subjects. Furnishings designed by Douglas include the pews, the stalls and the screens in the arcade. The east window contains stained glass which is said to be dated 1546; it depicts the Crucifixion. In the church are boards painted with the Creed and the Lord's Prayer in Welsh, dated 1809. Of the monuments, one is dated 1731, and another 1832.
The churchyard is oval in shape and contains the base of an old cross and the stone plinth of a former sundial. To the east of the church is a lych gate, adjoining which is a hearse house dating from about 1810.
References:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
