Martyr's Walk narrows, leading to a massive drawbridge.  The path ends
and a drawbridge of huge wooden beams adopts the way.  The sheer size of the
drawbridge awes you.  It is so large that forty men are used to close it. 
Looking over the edge, the moat churns quietly beneath, an occasional
serpent surfacing, skimming the top of the water.
