Castle Archdale

The former estate is situated near Lisnarick and Irvinestown, in the broader hinterland of Enniskillen, and the park is owned and run by the Northern Ireland Environment Agency.

PBY Catalinas and Short Sunderlands flew from Castle Archdale to protect Atlantic shipping from German U-boats.

Today's caravan site sits on the concrete maintenance area where aircraft were serviced, and a museum in the park holds exhibits from the World War II period.

Although Ireland maintained neutrality in World War II, a secret agreement between Eamon de Valera and the United Kingdom government allowed aircraft from RAF Castle Archdale to use the Donegal Corridor.

This allowed Fairey Swordfish aircraft from HMS Ark Royal to further attack with torpedoes, causing fatal damage to Bismarck.
