Penrhyn Castle was built in 1835-36 by Oliver Lloyd, a solicitor of Cardigan, as a “marine” residence, on land he leased in 1835 from Jonathan Rogers Powell, a solicitor of Haverfordwest, and Powell’s first wife Anne, née Tullet. Penrhyn Castle is marked on the St Dogmaels 1838 Tithe Map.
Described in 1870 as a castellated house with a flagstaff. On the death of Jonathan Rogers Powell in 1872, his son William Turner Powell sold Penrhyn Castle at auction in 1873 to John Rees of Hendre, for £450.
On 4 June 1877 John Rees and his wife Laetitia sold Penrhyn Castle to the Admiralty for use as a coastguard station – a substation to the St Dogmaels Coastguard Station. The roof was remodelled, the castellations were removed, and by 1891 the house had been converted into two self-contained flats – a ground floor flat and a first floor flat – to station two coastguards and their families
Penrhyn Castle Coastguard Station was closed after WWII and was sold at auction by the Ministry of Works in 1948. Recombined into a single dwelling in 1949 and porch added in early 1950s.
