One of four branches of the National Museum of Ireland, this museum is little changed from Victorian times and remains a fascinating repository of mounted mammals, birds, and other flora and fauna. Locals still affectionately refer to the place as the "Dead Zoo." The Irish Room houses the most famous exhibits: skeletons of the extinct, prehistoric, giant Irish elk. The International Animals Collection includes a 65-foot whale skeleton suspended from the roof. Another highlight is the very beautiful Blaschka Collection, finely detailed glass models of marine creatures, the zoological accuracy of which has never been achieved again in glass. Exhibitions include "Mating Game" and "Taxonomy Trail." Built in 1856 to hold the Royal Dublin Society's rapidly expanding collection, it was designed by Frederick Clarendon to sit in harmony with the National Gallery on the other side of Leinster Lawn. When it was completed, it formed an annex to Leinster House and was connected to it by a curved, closed Corinthian colonnade. In 1909 a new entrance was constructed at the east end of the building on Merrion Street.
