Very unusual to have this type of museum in a small Pueblo, it wouldn't be out of place in Malaga. Well worth visiting, it's free, educational for all age groups. Very well presented in a nice building. Spend half an hour or longer if you are more interested as it's only a small venue compared to other museums.
I've traveled a bit in Latin America and have been to a number of pre-Columbian museums so I've seen this stuff before. I was impressed by the excellent condition of many of the pieces here, especially the small clay figures. This small museum is free so what do you have to use. In the Benalmadena Pueblo.
