Because of the characteristic round shape of its churchyard, the Brecon cathedral is thought to be on the site of an earlier Celtic church, of which no trace remains. A new church, dedicated to St. John, was built on the orders of Bernard de Neufmarché, the Norman knight who conquered the kingdom of Brycheiniog in 1093. He gave the church to one of his followers, Roger, a monk from Battle Abbey, who founded a priory on the site as a daughter house of Battle. The first prior at Brecon was Walter, another monk from Battle. Bernard de Neufmarché also endowed the priory with lands, rights and tithes from the surrounding area, and, after his death, it passed to the Earls of Hereford, so giving it greater prosperity. The church was rebuilt and extended in the Gothic style in about 1215, during the reign of King John. In the Middle Ages, the church was known as the church of Holy Rood or Holy Cross, because it owned a great 'golden rood' which was an object of pilgrimage and veneration until it was destroyed in the Dissolution of the Monasteries in the 16th century. The smoke-blackened roof of its hall was built between 1237 and 1267.
In 1538 the Prior was pensioned off, and the priory church became the parish church. Some of the surrounding buildings were adapted for secular use; and others, such as the cloisters, were left to decay and later demolished. By the 19th century, the church was in poor repair and only the nave was in use. Some restoration took place in 1836, but major renovation of the church did not start until the 1860s. The tower was strengthened in 1914.
In recent years, some of the buildings in the cathedral close have been converted into a diocesan centre, a heritage centre and exhibition, as well as a shop and 'Pilgrims'' restaurant.
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.
