Today there are still castles all over Europe. Some are in ruins(废墟). But some built later are still in good repair and used even today. One example is Windsor Castle, which is a home to the British queen. It is in the country or Berkshire, not far from London.
Castles have walls around them. In the old days, soldiers would stand on the walls to guard the people in the castle. If enemies came they would shoot arrows(箭) and throw stones at them.
