Parliament Hill, formerly known as Traitor's Hill, is the gateway to London's Hampstead Heath. It's a natural haven to the north of London.

The 791 acre heath is an amalgam of the grounds of several large houses that once were in the area.

It's thought that Parliament Hill took its name from it being a point of defence during the English Civil War - a place for the troops loyal to Parliament.

Sixty years ago, Hampstead Heath was host to livestock, and in the 1930s, the cattle were reared to be sold through the London meat markets.

The upper parts of the hill are still unmown in summer, and is crisscrossed by a network of pathways.

The grasses on Hampstead heath are in fact specially bred farm grasses, a legacy from the time when the heath was an agricultural resource.

Public amenities include a racecourse and an adventure playground - it is also home to a flock of Flamingos.

Parliament Hill is the focal point of the Heath - Londoners own piece of the countryside at their back door.
