Fodor's Expert Review Museo El Polvorín

If the collection of this museum underwhelms, take a close look at the photo album next to the visitor log to see how much community spirit and sweat went into the restoration of El Polvorín, a former U.S. military munitions building, constructed in 1905. It reopened in 2008 as a museum, but not without an enormous amount of effort; the structure was little more than a shell. Today, it houses a small but interesting collection of objects and photos that tell the island's history (don't miss the story of Puerto Rico's first female mayor), along with several TVs with interesting oral history–based documentaries on loop.
