We listened to the tour with a Russian-speaking guide, it was very interesting. The history of the construction of the towers and James Joyce’s stay in it is also interesting. Very beautiful view from the roof. I recommend the guide Yunona Dikareva, she really tells a fascinating story

Chanced upon this by accident on a day trip with my partner out of Dublin. It's an early 19th century Martello tower built by the British to keep Napoleon out of Ireland that then became a hangout for early 20th century bohemians including - for just six nights - James Joyce. Even though he wasn't there for long, it inspired him to start writing Ulysses. A chatty lady gives you the whole story when you come in. Put it this way - it's very, very different. Your visit won't extend much beyond 30 minutes but worth doing to mess with your mind a bit.

Great little museum amongst the stunning location of Sandycove. The staff are so helpful and informative and go out of their way to help in any way possible. The tower is fascinating, especially the view from the rooftop over Sandycove.

Visited because it was free, but stayed because we got an excellent 15 min tour from JP, one of the volunteers. We have kids from 10-14 and both kids an adults got something out of it. Literary history of Joyce and military history of the Martello tower. You can't beat a free tour from a local expert. Note: the winding stairs to access the upper levels required degree of mobility and agility. Would not recommend going above the ground level if you are very young or very old. Enjoy the walk about the forty foot and sandy cover area afterwards. Parking is limited in the area, but high turn over with the swimmers, but do not recommend driving a large vehicle on the streets. Better to walk.
