One of the most interesting things that happened during this summer's unusual and prolonged heatwave in Britain and Ireland was the mysterious reappearance of historic gardens and buildings. Outlines of old houses and villages that had been lost and forgotten for centuries emerged and brought the past vividly to life, if only for a short few weeks. Why does this happen?
Apparently it's caused by the depth of soil, or lack of it. Parched grass in extreme temperatures dies off when there is less soil under it. A hard area, such as a wall or pathway, will show up as a brown scorch mark.
What was once a 17th century parterre, or formal garden, at Chatsworth House in Derbyshire reappeared and was photographed from above. In this first photo, the hard landscaped areas of Chatsworth's parterre are clearly visible in the modern lawn.
In the second photo, we can see the illustration of the formal design dated 1699 and it's obvious where the original paths belonging to this are still lying beneath the lawn today. The 1699 design was covered over when Lancelot 'Capability' Brown created his more natural landscape. I'm grateful to Chatsworth for allowing me to use their photos. They weren't certain whether scorch marks of this historic parterre had ever appeared before.
The lost village of Edensor
What was also fascinating at Chatsworth was the reappearance of parts of the lost village of Edensor, which has only been seen a few times in the last two hundred years. The last time was an extremely dry summer in the 1940's. When a drone camera took photographs from the air during this summer's heat wave, outlines of the high street, a school and other buildings that had been demolished to make way for Capability Brown's new natural landscape in the 18th century were clearly visible. The new village of Edensor was completed in 1842.
Prehistoric site discovered near Newgrange in Co. Meath, Ireland
Closer to home in Ireland, a 'giant henge' structure appeared on a tillage farm near historic Newgrange in Co. Meath. Drones photographed the outline of a prehistoric archaeological site approximately 200 metres in diameter. It's thought that this might have been built 500 years after Newgrange, which dates from 3,000 BC. The summer drought provided archaeologists a once in a life-time chance to discover outlines of important sites that we didn't even realise existed.
