The tower of the unknown purpose - again

Froma different angle this time - I know I have never blipper it from this angle before because I was lost and found out that I was on a ded end road that went along fdor 2 miles then just sort of stopped by some old hall with an archway - apparently it is now a cattery

I have it marked down as a blip for the summer when the sun is ina better position

Anyway - I also discovered that when the doc. says you have asthma then going out in the cold with a strong wind and cycling as fast as you can up steep hills can be a bad idea - S told be off!!

Still have no idea why this tower was built
