A very nice Museum about the history of Merida. There are cards in Spanish and English which tell you about the history of the city and it gives a good overview for someone, who doesn't know anything about the city's history.
It is free, but there aren't that many things to look at, which is fine for the cost. On the ground floor there is a history exhibition and on the upper two floors various artists present their art.
