Acting as a major cultural destination since 1895, the De Young Museum reopened in October 2005 in a facility designed by Swiss architecture firm Herzog & de Meuron and Fong & Chan Architects in San Francisco. The building is magnificent and from the observation tower you can get a great view of the park. It is open, airy and massive. It also has a perforated and embossed copper facade which goes very well with the greenery around the museum. The museum houses the world-renowned American Painting and Sculpture collection, dating from the 17th to the 20th Centuries. Primitive Art is highly represented with extraordinary pieces of Native American Art (from the ancient Teotihuacan City), African Art (statues and potteries) and Oceanic Art (shields, dance dress and masks). Admission is free the first Tuesday of each month.
