Also known as the Privy Chamber, this room, created for Charles II in the late 1600s, is used by The Queen for private audiences. It was in this room that Her Majesty hosted an audience with Pope Benedict XVI in 2010.

Each year, during Lord High Commissioner's week, morning prayers are held in this room.

The sumptuous ceiling is one of the most elaborate in the Palace: each corner bears the cypher of Charles II - back-to-back "C" and "R" - lions and unicorns, from the Royal Coat of Arms, adorn alternate sides and flowers and foliage hang from the ceiling.

The 17th-century French tapestries in this room, which illustrate scenes from the life of Diana, have  been associated with the Palace since 1685.
