sutton park
The 900 acres of Sutton Park was given to the people of Sutton Coldfield in 1528 by King Henry VIII, it is said at the request of Bishop John Vesey.
It's a widely held belief that any citizen of Birmingham can graze their sheep on the land — and some do, along with cattle and wild ponies.
Wikipedia says: It comprises a mix of heathland, wetlands and marshes, with seven lakes
and extensive ancient woodlands which cover approximately a quarter of
the Park. There's evidence of prehistoric occupation of the land, including an ancient tumulus under what is now the Queen's Coppice. It also contains a preserved section of the ancient Roman road of Icknield Street near the Royal Oak Gate, and there are earthworks of an ancient encampment near Blackroot Pool. It was a Royal Forest in the Anglo-Saxon kingdom of Mercia, and an established Norman deer park.
In 1997, English Heritage designated it a National Nature Reserve.
