Expiatory Church of the Holy Family Museum, Barcelona

Templo Expiatorio of the Sagrada Família is the unfinished and most expensive project by Antoni Gaudí, the great architect. This unique exhibit includes plans, drawings, photographs and models related to the construction of the temple. It also houses pieces made from wrought iron, bronze and wood. Visitors can see how the temple was devised and its origins. The museum is located in the crypt of the basilica and you enter from the side of the Passió façade (Carrer Sardenya). There is a lift that takes visitors to one of the towers from which there is an excellent view over this unfinished though magnificent construction.
