Rattlesnake hut

The tower in the photo does not come from Harry Potter, but we can find it in the Czech Republic near the town of Beroun, in a quarry near Serbia. It is a former, hundred-year-old reflector tower used to illuminate the quarry during mining.
Amazingly photogenic object.
I photographed this tower with a Samsung i8910 HD mobile phone and edited it in the Photophiltre program.
