St Decuman's Church is on a very early Christian site and is dedicated to Saint Decuman. It was the 'bishop-house' of the cantref of Penfro and one of the seven principal churches in Dyfed under medieval Welsh law. It is constructed of rubble stone under a slate roof which carries a bellcote. The nave and chancel are possibly 13th century and the transept, chapel and tower 14th century.
The font, in the north porch, is 12th or 13th century; the nave has a small Norman font. The church contains a number of tombs and memorials, including two recesses and wall-mounted coffin lids. The oldest dated memorial is a 1716 baroque monument to F Powell of Greenhill. The pulpit and lectern are 19th century, and windows range from the 19th and 20th centuries, as recently as 1960.

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.
