The heatwave has continued to reveal details of England’s ancient past to archaeologists.
Surveys from the air have revealed Neolithic ceremonial monuments, Iron Age settlements, square burial mounds and a Roman farm for the first time.
Historic England said the weather “provided the perfect conditions” to see the crop marks because of the lack of moisture in the soil.
They include two Neolithic monuments discovered near Milton Keynes.
The long rectangles near Clifton Reynes are thought to be paths or processional ways dating from 3600 to 3000BC, one of the oldest of their type in the country.
Numerous features in a ceremonial landscape near Eynsham, a few miles north-west of Oxford, date from 4000BC to 700BC.
Monuments to the dead, a settlement and a circle of pits can be seen in crop marks on the field in an area that is already protected.
In each case the remains are revealed as differences in colour or in the height of crops or grass.
Duncan Wilson, chief executive of Historic England, said: “The discovery of ancient farms, settlements and Neolithic cursus monuments is exciting.
“The exceptional weather has opened up whole areas at once rather than just one or two fields and it has been fascinating to see so many traces of our past graphically revealed.”
Historic England uses aerial photography of crop marks to produce archaeological maps to help determine the significance of buried remains.
This can help when making decisions about protecting them from future development or damage caused by ploughing.
Aerial investigation and mapping manager Helen Winton said: “This is the first potential bumper year in what feels like a long time.
“It is very exciting to have hot weather for this long. 2011 was the last time we had an exceptional year when we discovered over 1,500 sites, with most on the claylands of eastern England.”
