It's more art [ceramics and photos of ancient cave art] than anything else, so it's defined here as an art museum, but the lowest floor does include some early trades. It's a striking Renaissance building, previously La Casa de la Comunidad and home to the first office of the council.
Why it doesn't get a bit more enthusiasm from the guidebooks beats me. There are careful presentations of early industry and portrayals of cave art in the basement, and whole floors above are given respectively to the Roman age and the Iberian age [6-4th ceturies BCE - the best I have seen for this], as well as great ceramics presentations [rivalling the national museum in Valencia] on other floors.
Wonderful views from the arcaded floor above the exhibits. And it's FREE!
