A real find. This museum tells the story of General Luperon through the artifacts of the day as well as through an interesting film (as others have said -- insist on seeing the movie first, otherwise the tour is does not make a lot of sense). The building is a replica of the house in which this Dominican hero died and it is beautifully presented. The guides are very friendly but their English is quite limited. I visited twice -- once with a Spanish speaking visitor and realized how much more informative that guided tour was then the English one. Even though the museum is new the signage and information on the exhibits are only in Spanish and the section with audio-clips was only in Spanish. Too bad they did not follow the lead of the Taino Museum (in Samana) or the national museum in Santo Domingo and have English language printed materials and/or audio materials.
The Museum is conveniently located near the Central Park, the Amber Museum (interesting but a little too commercial), The Meeting Place (a volunteer information center where you can get free maps, info), and the Melacon (the beachfront boulevard) where there are lots of little huts and restaurants and which leads you on a short walk to the colonial fort at the end.
Oh, yes, there is a truly nice cafe at the museum which is located in the courtyard. Ideal for a coffee and "treat". And there is an elevator.
Unfortunately, the museum subscribes to "make the tourists pay" as non-Dominicans are charged twice what the local population is charged. This policy plus the lack of English and the fact that one has to insist to see the DVD (there are English subtitles though quite flawed) at the beginning of the tour means that I would not rate this a 5 star.
