The room takes its name from its use during World War II, when President Franklin Roosevelt used it as a situation room where maps were consulted to track the war's progress.
The Map Room is furnished in the style of English cabinetmaker Thomas Chippendale and includes two stuffed-back armchairs that may have been built by Philadelphia cabinetmaker Thomas Affleck. Today the room is used for television interviews, small teas, and social gatherings.
This little cache is located just off Aston Lane South, in the Whitehouse Industrial Estate, Runcorn. Hopefully you won't need a map to find it!
