The latest in the series in which we ask you to identify where in London this picture was taken and what it’s of. If you reckon you know the answer, leave a comment below. We’ll reveal the answer early next week. Good luck!

And the answer is…this is part of the decorative facade of the Middlesex Guildhall which stands opposite the Houses of Parliament in Parliament Square. The building, which dates from 1912-13 and stands on the former site of the Westminster Abbey Sanctuary Tower and Old Belfry (where fugitives from the law could seek sanctuary), is now home to the Supreme Court and the Judicial Committee of the Privy Council.

Designed by architect James Gibson, it is the latest in a series of buildings which stood on the site which have served as courthouses and the headquarters of the Middlesex County Council (the first Middlesex Guildhall was built here in 1889). Described by Nikolaus Pevsner as “art nouveau Gothic”, it features a series of medieval-looking decorative friezes and sculptures by Henry Charles Fehr.

The image pictured above shows one of the friezes – this one of the Duke of Northumberland offering the ill-fated Lady Jane Grey the Crown (known as the “Nine Days Queen”, she was later imprisoned and eventually executed on 12th February, 1554). Others show King John handing the Magna Carta to the English barons and the granting of the charter of Westminster Abbey.

It was refurbished for use of the Supreme Court in 2007 and the court has occupied it since its creation in 2009.

Interestingly, according to Ed Glinert of The London Compendium, it was here that courts martial were held of those suspected of giving aid to the enemy during World War I.
