I've stopped by here three times now. This is not a large museum, but it is very well thought out and informative . I'd guess we spent about a half hour talking to the docents, reading and looking at the displays and viewing a short video. This is the actual site of the first transatlantic wireless telegraph transmission, and has very informative displays and knowledgeable docents. I can't imagine not taking a side trip to it when in the area.
