I revisited the Parkland walk a year or so later with my brother Tariq who enjoyed it as much as me. I took some more photos but can't bloody find them! However my brother fortunately took some, including the FAB one above and saved the day, as it were!
The picture above shows what I presume is a representation of a Green Man? The sculpture/statue was made by God knows who and is an absolutely fantastic addition to the walk. I was gobsmacked when I came accross it.
