The Isle of Doagh hasn’t been an entire island since the end of the last Ice Age. It is now a smaller peninsula within the Inishowen peninsula, bounded in the west by Pollan Bay on the Atlantic Ocean and Trawbrega Bay in the west.
There is an extensive dune system on the Isle of Doagh, which is renowned for its flora and fauna.
On a large rock, named Friars Rock to the northern end of Pollan Bay, stands the ruins of Carraickabraghy Castle. It is commonly accepted that the castle was erected before 1600 by Phelemy Brasleigh O’Doherty. At that time Carrickabraghy would have been almost an island, with little ground separating it from the mainland.
The Doagh Famine Village is located here. This open-air museum contains examples of thatched buildings and traditional lifestyles. Attractions include recreations of an Irish wake, Orange Hall, Presbyterian Meeting House, mass rock, hedge school, eviction scene and Republican Safe House.
