Cyfarthfa Castle, home now to the Merthyr Tydfil museum but was occupied by the Crawshay family from 1810 until 1889. To us now the original £30,000 cost seems a snip but in those days such a sum required deep pockets. A wonderfully grand place set in a raised position which enabled the family to admire their source of extreme wealth down in the valley below. The furnaces glowed red day and night reminding them of their ever increasing income.
