Here is one of the finest Jacobean mansions in Britain. Designed by John Thorpe and completed in 1612, it has survived bombing, restorations and alterations remarkably intact, although the original chimneys were replaced in the 19th century. The south extension was added in 1877 by Norman Shaw. Outside, there are two walled gardens and a Mulberry tree said to be the first in Britain. It was planted by James I.
