The organ in Parr Hall.
Occasionally you trip over surprising things in the undergrowth of history. One thing that surprised me was when I started to get hints of a world famous organ in the old Bracewell Hall. Eventually I found that the owner, William Turner, had commissioned Cavaille-Coll of Paris to build him an organ in 1870 which he later enlarged. When he left Bracewell he took the organ with him to I think it was Ketley Hall and later it was moved to Parr Hall in Warrington. See THIS for a slightly erroneous account of the organ in Cheshire Life. Despite its precarious status at the moment it still survives and is played regularly.
