St Fagans National History Museum
For the family historian visiting Wales, the St Fagans National History Museum is a must see. Located on a large and picturesque site a few miles outside Cardiff, it is one of Europe’s leading museums and probably the first to save and restore important domestic buildings by taking them apart brick by brick and stone by stone and rebuilding at St Fagans.
Whatever part of Wales your ancestors came from you will be able to see examples of the vernacular homes they might have lived in. http://www.museumwales.ac.uk/stfagans/
18th-century Welsh gentry estate - with house, walled gardens and home farm This rare example of a self-sufficient 18th-century Welsh minor gentry estate has survived virtually unaltered. The villa, designed in the 1790s, is the most complete example of the early work of John Nash. It has its own service courtyard with dairy, laundry, brewery and salting house, and walled kitchen gardens (with all its produce for sale when in season). The pleasure grounds and ornamental lake and parkland provide peaceful walks. The Home Farm complex has an impressive range of traditional, atmospheric outbuildings and is a working organic farm with Welsh Black cattle, Llanwenog sheep and rare Welsh pigs.
Dinefwr Castle, Carmarthenshire
12th-century Welsh castle, historic house and 18th-century landscape park, enclosing a medieval deer park A magical land of power and influence for more than 2,000 years, Dinefwr Park and Castle is an iconic place in the history of Wales. Two forts are evidence of a dominant Roman presence. The powerful Lord Rhys held court at Dinefwr and influenced decisions in Wales. The visionaries, George and Cecil Rice designed the superb 18th-century landscape that you see today. The 'hands-on' Newton House gives visitors an atmospheric circa 1912 experience. Exhibitions on the first floor tell Dinefwr's story and inspire visitors to explore the castle and park.
Canolfan Hywel Dda Centre, Whitland, Carmarthenshire
Hywel Dda was born towards the end of the ninth century. In 928 AD he made a pilgrimage to Rome and by 942 AD he ruled over most of the country and claimed the title "King of all Wales". The Prologue to the early manuscripts state that he then summoned representatives from each commote in his kingdom to an assembly at “The White House on the Taf in Dyfed” for the purpose of codifying the laws. This legal system became known for its wisdom and justice and was in force in Wales until the Act of Union with England in 1536.
