Knebworth House, Knebworth, Hertfordshire: the central arch of the 17th century screen in the Great Hall

NOTES: The original house was built c. 1500 by Sir Robert Lytton. It was part demolished and rebuilt in 1813-1816 by J . B. Rebecca in a Tudor/ Gothic style. Then in 1843-1845 it was extensively remodelled by the architect Henry Edward Kendall, who added much of the sculptural embellishments on the previously modest towers.
