Living history museum with 1st person actor/interpreters: Since the house ceased to be a family home, it has been completely renovated. It now reflects its general appearance in the mid-seventeenth century although there is clear evidence both of earlier features and of some later adaptations. A detailed appraisal of the architectural features and merits of the house has been made both by the Historic Monuments Division of the Welsh Office and by the Welsh School of Architecture which has been responsible for overseeing its renovation. The work of restoration of Llancaiach Fawr has been carried out to high technical standards, and using many contemporary techniques such as rough lime-based plaster for walls and ceilings. There has been much painstaking restoration work. The house is now restored to its 1645 appearance during the British Civil War, and has become one of the leading 'living history' sites in the UK.
