Callow Hall. A large hall in woodlands at the south end of Mapleton village. Private dwelling house of considerable beauty. (1) Grade II listed building of 1848-52 by Henry Stevens of Derby. Built in the Elizabethan style. The house was originally designed on a much more ambitious scale but was reduced in size before building commenced. (2) In 1848 the Derby architect Henry Isaac Stevens designed an ambitious Jacobethan house to go on a moiety of a former estate which lay between Ashbourne and Mapleton. The client was John Goodwin Johnson, whose like-named father (died 1838) had been an opulent Ashbourne attorney who had adopted the surname of a Wirksworth heiress. He married a daughter of Francis Beresford of Ashbourne, which had added to the estate upon which there appears to have been a previous house called the Callow. Callow Hall was not built exactly to Stevens' original design; for example a planned largish tower was reduced in scale, a bowed window became an oriel and an ornate conservatory vanished entirely. The Hall is built of rough-rocked ashlar of carboniferous limestone with dressings and porch of Keuper sandstone and has a slate roof. It belonged to a succession of owners before being sold in November 1982 to a buyer who opened it as a hotel and restaurant, with self-catering units and fishing. The cellars were apparently used to store War Department archives during World War Two, and a TV series called The Mallens was filmed there in the 1980s. (3)
