In the trench are little piles of white stones. It's clear that the stones were once parts of a laudatory statue set up by the previous administration. It's a pity that with every new election, icons are dragged off to be dismantled, since the changing winds of politics means that new statues need to be carved constantly.
The stone chips, being marble, can be heated and dissolved into a kind of lime, which we use for covering out walkways, gardening, and as ballast.
