The (rather weird) <a href="//commons.wikimedia.org/wiki/Well" class="mw-redirect" title="Well">well</a> in the <a href="//commons.wikimedia.org/wiki/San_Calimero_a_Milano" class="mw-redirect" title="San Calimero a Milano">crypt of San Calimero church</a> in <a href="//commons.wikimedia.org/wiki/Milan" class="mw-redirect" title="Milan">Milan</a> (Italy). The legend has that the corpse of bishop <a href="//commons.wikimedia.org/wiki/Saint_Calimerus" class="mw-redirect" title="Saint Calimerus">Saint Calimerus</a> was thrown, in scorn, into this well, after his martyrdom (an event whose actual occurrence is uncertain, though). The water of this well used to be deemed "miraculous". Picture by <a href="//commons.wikimedia.org/wiki/User:G.dallorto" title="User:G.dallorto">Giovanni Dall'Orto</a>, May 5 2007.
