The small chapel, decorated in the Gothic Revival style with shimmering mosaics and Byzantine influences, is tucked away in Pearson Square, in a quiet corner of London’s West End.

It was built in the courtyard of what was the Middlesex Hospital, serving its staff and patients. When the hospital was demolished the chapel was retained and restored, with a new development built around it.

It’s no longer regularly used for services, but is used for community events and concerts and is open to visitors wanting some quiet contemplation.

The monarch’s Christmas message has often been recorded in Buckingham Palace or Windsor Castle.

But there have been exceptions, most recently in 2010 when it was filmed at Hampton Court Palace, and before that in 2006 at Southwark Cathedral. In 2003 the speech was recorded at an army barracks in Windsor.

The run-up to Christmas has seen the King attending a series of seasonal events, including a Christmas market in Battersea, a service remembering those persecuted because of their religion and an event in Walthamstow celebrating the diversity of the local community.

The King’s speech on Christmas Day follows a tradition dating back to 1932, when George V made the first Christmas broadcast.

That first speech was scripted by Rudyard Kipling, who lay in state in the Fitzrovia Chapel before his funeral in Westminster Abbey.
