History

Built c1820 as house for the doctor to Penrhyn Slate Quarry and extended in mid-C19 during the ownership of Dr Hamilton Roberts, who in April 1847 used ether as an anaesthetic during the amputation of a quarryman's leg. Ether had first been used in this way in Boston, Masachusetts the previous year and its use by Roberts was the first occasion on which it was used in Wales. Much of the fine garden planting, including the purple beech, redwood and Cedar of Lebanon trees was carried out by Roberts.
