Concentric Castles
The Concentric castle was developed in the 12th and 13th Centuries and offered the best protection against attack.The main feature of the concentric castle is its walls. An inner wall built of thick stone with turrets positioned at intervals is then surrounded by an equally thick but lower stone wall. The walls are built at different levels so that archers on the inner walls can fire over the archers on the outer walls.�
Motte and bailey
Motte and Bailey Castles are the earliest castles. The Motte was a large hill made of earth on which was built a wooden keep or lookout. The outer edge was then surrounded with a large wooden fence called a palisade. The Bailey was the part of the castle where people lived and animals were kept.
