Greenheart

That is the name of this sculpture at Watergate Forest Park where we went for a walk today.  Pretty muddy underfoot.  The park is located on the site of the former Watergate Colliery and opened in 2000.  It seems to be very popular with dog walkers.

Not entirely sure what the sculpture is meant to represent but found this on the net:-

'Great North Forest commissioned William Pym to create five Forest Gateways for newly planted sites on the urban fringe in Tyne and Wear, which are all linked by a history of coal mining and a new future as environmental resources for local communities to enjoy.'
