from life - roman theater near Alcudia (Mallorca). I was wondering myself about the trapezoid holes cut in the stones at the sides of the theater. I later read at wikipedia that after the decay of the roman empire the theater was used as an graveyard and the holes where in fact graves. Thought about our huge soccer stadiums, would they also be used in such ways if out civilization crumbles one day? For a soccer fan not the worst place to be buried...
