Fanhams Hall is an 18th‑century Queen Anne style country house at Wareside, just outside Ware in Hertfordshire.  It is a Grade II* listed building and now operates as a hotel and events venue.
The original early‑18th‑century brick house was enlarged and encased around 1901 into a three‑storey Jacobean‑style mansion with stone dressings.  Inside, it has Arts and Crafts style decoration, including plasterwork by L. A. Turner and stained glass by Morris & Co. in the library.
Fanhams Hall was the birthplace and home of Sir Henry Page‑Croft (later the first Lord Croft), who served as Winston Churchill’s Under‑Secretary of State for War until 1945.  His sister Anne, later Lady Brocket, also lived there and returned to the house after her husband Lord Brocket’s death, remaining until 1949.

Pencils spin on their own, radios turn on and off independently, and cries of children echo despite none being present.
