Ah yes that wall catches many an eye,..at the end of my garden i have a wire fence and gate,..this leads to a pathway with that stone wall on its right,..it leads right around to the front of the house,..mainly used to carry heavy stuff into the garden or for the house,..rather than having to go through the front door.
The wall is a boundary wall and within it is a park and Church and a few houses,..some shots below to give you an idea,..some parts are covered with Ivy and stuff.
