National Trust property built as a Roman folly located on a very prominent and visible hill outside Sunderland.
The Doric tetrastyle monument is 30 metres (98 ft) long, 16 metres (52 ft) wide and 20 metres (66 ft) high. The columns are each 2 metres (6 ft 7 in) in diameter. It was designed by John and Benjamin Green and built by Thomas Pratt of Sunderland.
Old failed and damaged metal halide floodlights were ready for renewal and in partnership with the city council and PFI contractor and following extensive trials the PCK compact reach was selected. A blacksmith manufactured special housings locally. The scheme is controlled by a Pharos LPC1 and is part of the strategic lighting upgrade by the council.
