Clifford's Tower in York

I'm standing in front of Clifford's Tower. Its part of what's left of York Castle. Originally built by William the Conqueror the castle has been changed over the years. The original wooden tower was burnt down in 1190 and rebuilt. In the middle of 13th C Henry III decided to knock it down and build an entirely stone tower. Wooden castles aren't really that useful, especially against us dragons. For people that can't fly (I don't know how they manage) there are steps going up to the tower. The path used to wind round the mound up to the tower, which sounds more fun than the straight steps there now. Nobody knows why its called Clifford's Tower - they could tell you that before making you climb all those steps to read the information inside the tower.
