This can be filed in the box called 'little things that please me'.
Walking along Lower Thames Street, at the junction with St Mary-at-Hill, I noticed some markings in the pavement that, at first perplexed me:
Ooh – circles and squares in patterns – my kind of thing, here in what looked at fisrt glance to be a variety of designs, some with borders, some with alternating circles, some more grid-like.
And then it dawned on me that these are simply the marks left by the bottom of scaffold poles where the soft surface, possibly warmed in the summer sunshine, this being south-facing, has taken on the pattern of the bottoms of the square footers, or whatever they are called as there's probably a specific name for these things.
I have seen these in a few places, but had never understood what they were or how they were formed. Thank you for clearing this up.
