Situated on top of Castlehill the castle is Edinburgh's most famous attraction. In fact in the UK it is second only to the Tower of London in visitor numbers. There is a long and vibrant history to this place (see City Origins). It is well worth a visit if only for the views across the city. There are many things to see including the ancient Scottish Crown Jewels, a war museum, chapel (the oldest building in the city), exhibitions, medieval ruins and of course the gun fired daily at 1pm. And if you are lucky you may see a ghost or two!
