Nottingham Castle Museum and Art Gallery

Nottingham Castle is a Stuart Restoration-era ducal mansion in Nottingham, England, built on the site of a Norman castle built starting in 1068, and added to extensively through the medieval period, when it was an important royal fortress and occasional royal residence. In decline by the 16th century, the original castle, except for its walls and gates, was demolished after the English Civil War in 1651. The site occupies a commanding position on a natural promontory known as "Castle Rock" which dominates the city skyline, with cliffs 130 feet high to the south and west.

William Cavendish, 1st Duke of Newcastle, started to build the mansion in the 1670s; it was completed by his son, the 2nd Duke of Newcastle. This ducal palace was burnt by rioters in 1831, then left as a ruin until renovated in the 1870s to house an art gallery and museum, which remain in use.
