Old Locked Door exposure no. 9

Very interesting construction! Can't remember I ever seen this X shape on double doors in Sweden, must look around and keep my eyes open (perhaps I just haven't noticed it?) If I find something similar, or very different way of placing the diogonals in these four squares I will post a picture of it. Thanks for the picture, very nice, particular with round grass (?) in the foreground! /Bertil

Thank You. The design of the doors reminds me of the Union Jack. The round grass is actually a manhole cover. The sewer gas must be feeding the grass through the seams.
