Long gallery is an architectural term given to a long, narrow room, often with a high ceiling. In British architecture, long galleries were popular in Elizabethan and Jacobean houses. They were often located on the upper floor of the great houses of the time, and stretched across the entire frontage of the building. They served several purposes: among others, they were used for entertaining guests, for taking exercise in the form of walking when the weather was inclement, and for displaying art collections.

A long gallery has the appearance of a spacious corridor, but it was designed as a room to be used in its own right, not as a means of passing from one room to another. In the 16th century, the seemingly obvious concept of the corridor had not been introduced to British domestic architecture: rooms were entered from outside, or by passing from one room to another.

Later long galleries were built in Victorian houses such as Nottingham Castle.

John Whitaker "Jack" Straw (born 3 August 1946) is a British Labour Party politician who has been the Member of Parliament (MP) for Blackburn since 1979. He served as Home Secretary from 1997 to 2001, Foreign Secretary from 2001 to 2006 and Lord Privy Seal and Leader of the House of Commons from 2006 to 2007 under Tony Blair. From 2007 to 2010 he was the Lord High Chancellor of Great Britain and the Secretary of State for Justice, appointed as part of Prime Minister Gordon Brown's first Cabinet. Straw is one of only three people to have served in Cabinet continuously from 1997 to 2010 (the others being Gordon Brown and Alistair Darling).

When the Labour Party lost power in May 2010, he briefly became the Shadow Lord High Chancellor of Great Britain, Shadow Secretary of State for Justice and the Shadow Deputy Prime Minister, but stood down from the frontbench after the Labour Party elected a new Shadow Cabinet.

Straw was born in Buckhurst Hill, Essex, England. One of his maternal great-grandparents was a Jewish German immigrant. Straw was brought up at Loughton, Essex by his mother, Joan Sylvia Gilbey on a council estate after his father Walter Arthur Whitaker Straw, an insurance salesman, left the family and condemned them to poverty. Walter Straw had been sent to prison in 1939 for being a conscientious objector.
