The Long Gallery, completed in 1601, was built by Sir Robert Sidney and his wife, Barbara Gamage.

Long galleries were very fashionable in the Elizabethan period. They were used for taking exercise and showing off portraits, tapestries and furniture.

This Long Gallery is unusual in being lit from three sides and the fine panelling is original. The ceiling is a 20th century exact replacement for the original, decorated with many Tudor and Sidney family symbols.
