National Museum of Ireland - Natural History Museum

This museum is similar to the Grant Zoology Museum except it is a lot larger and has more stuffed animals. It didn't have as many unusual specimens as the Grant Zoology Museum, more your stand animals that you would see at a zoo or aquarium, but they had some huge specimens like elephants and whales. If you like the series Penny Dreadful I believe this museum was in there or one that looks very similar.
