The Wallace Collection is a museum located in London, England. It is known for its exceptional collection of fine and decorative arts from the 15th to the 19th centuries. The collection was amassed by Sir Richard Wallace, a wealthy art collector who bequeathed it to the British nation in 1897.

The museum is located in Hertford House, which was built in the 18th century as a private townhouse for the Marquess of Hertford. The building was extensively renovated and expanded in the 19th century to accommodate Wallace's collection.

The collection includes over 5,500 works of art, including paintings, sculpture, furniture, porcelain, and armor. One of the highlights of the collection is the extensive collection of 18th-century French decorative arts, including Sèvres porcelain, furniture, and snuffboxes.

Other notable works in the collection include paintings by Rembrandt, Velázquez, Titian, and Frans Hals, as well as a large collection of armor and weapons from around the world.

In addition to the permanent collection, the Wallace Collection also hosts temporary exhibitions and educational programs for visitors of all ages. Admission to the museum is free, and it is open to the public seven days a week.
