Located in what was the gatehouse of Westminster Abbey, this small prison dates from 1370.

It was built by Walter de Warfield, then the abbey’s Cellarer, and featured two wings, built at right angles to each other.

Under the jurisdiction of the Abbot, the prison had two sections – one for clerics and one for laymen. The Abbey’s Janitor was its warder.

Among the most famous inmates was the Cavalier poet Richard Lovelace who was imprisoned for petitioning to have the Clergy Act 1640 annulled. While inside, he wrote the famous work, To Althea, from Prison which features the famous lines: “Stone walls do not a prison make, Nor iron bars a cage”.

Other notables include Sir Walter Raleigh, held here on the night before he was beheaded in Old Palace Yard on 29th October 1618, diarist Samuel Pepys – detained for a few weeks in 1689 on suspicion of being a Jacobite (but released because of ill health), and Gunpowder Plot conspirator Thomas Bates.

Falling into a state of decay, the prison was demolished in 1776-77 (although one wall stood until the 1830s). A gothic column, the Westminster Scholars’ Memorial which is also known as the Crimea and Indian Mutiny Memorial, now stands on the site.
