Great natural history museum, better and larger than the one in the Botanical gardens. There are multiple rooms with exhibitions about the natural history of Madeira, with videos and a film room playing constantly. Outside, there is a fantastic small garden with a variety of plants. Unfortunately, the aquarium section was undergoing renovation, so it was shut. Well worth a visit. It's free to enter and there are toilets available which were immaculately clean, well done the people who look after these.
