A castle was built to withstand attack from enemy. Castle builders added many defensive features to make their castles difficult to attack. Many castles were built on high ground with clear views of the surrounding land.

  • Attackers were easy to shoot whilst swimming or rowing across the moats
  • Filled with water.
  • Cut down on tunnelling under the castle.

  • Steep banks of earth or rubble.
  • Attackers had to climb over them to get closer to the castle.
High walls
  • Very high making it hard for attackers to climb over.
Curtain walls
  • Tall thick curtain walls surrounded the castle like a strong shield.
  • Few doors in the wall limited access to the castle.
Flanking Towers
  • Towers built as part of the curtain wall.
  • More difficult to capture.
  • A good early example of a castle with flanking towers is Framlingham in Suffolk. Along the curtain wall, at intervals, are thirteen square or rectangular towers.
