Record-breaking heat and prolonged dry weather across Britain have caused parched grass to reveal the outline of a "lost" 17th-century formal garden, as scorched lawns expose buried archaeological features that would normally stay hidden. The phenomenon, known as a parchmark or cropmark, occurs when vegetation above buried walls, paths and foundations dries out and dies at a different rate to the surrounding grass, tracing the ghostly footprint of structures long since removed or built over. Such discoveries matter because they offer archaeologists and historians rare glimpses of historic landscapes without any need for excavation.

The garden dates back roughly 400 years and its elaborate layout, including paths and planting beds, became visible only once the heatwave had sufficiently stressed the grass covering the site. Similar heat-induced revelations have become increasingly common during Britain's hottest and driest spells, with historic sites, former estates and archaeological remains periodically resurfacing in aerial and ground-level photographs as a striking, if unintended, consequence of the extreme weather.
