A brilliant attraction with something for everyone. A fascinating insight into the history of Greencastle, as well as Inishowen more widely. The VR experiences were wonderfully engaging and heightened the experience. For such a small fee, the Museum is more than worth it!

Olena Anoricheva

The museum is excellent! It is really really worth it, especially for teenagers and adults. I didn’t expect the museum to be so great! Very educational. Everybody who’s interested in ships, lighthouses, radio technology and ship wreckage findings should visit it. There’s even a virtual reality simulator to play as a Lieutenant of a ship.
