The gardens were designed by André Le Nôtre, who also worked at Versailles. The museum holds 5000 pieces of art comprising 420 French paintings and a collection of 612 weapons. But it is mainly dedicated to Spanish art with the largest collection in France, including 200 paintings, against 166 in the Louvre, as well as 140 sculptures, coins from Antiquity to the 19th c. and nearly 1000 drawings and prints, like the complete four series of Goya (Caprichos, Disasters of War, Los Disparates and La Tauromaquia), the Gaudí serie by Joan Miró and 83 prints by Salvador Dalí. Its paintings range from the 14th century to the present day, with Francisco Goya himself represented by three paintings given by the son of the painter Marcel Briguiboul in 1894, The Junta of the Philippines (c. 1815, Goya's largest work), Self-Portrait with Spectacles (in French) (c. 1800) and Portrait of Francisco del Mazo (in French) (c. 1815-1820).
