When Richard became master of this castle, he had a precarious relation with
the new king of France, Philippe-Auguste. Philippe was the son that very
Louis VII, ex-husband of Richard's mother Eleanor and who had a few years
earlier burned this castle. Richard and Philippe had actually been very
close as times and they had gone off to the Third Crusade as "brothers" along
with Eleanor who was one of the few women crusaders of the age. That
crusade seemed at first a great success but soon turned to disaster.
Richard was even taken hostage, and Philippe was soon to return to Europe.
It was during Richard's captivity that the legends of evil rule came forth in
England and in these lands as well. This is the time of Robinhood.
On this side of the channel and upon Richard's return the French and English
thrones were at death's throes. Richard was king of England, but his
home is here and he would put all his energies into the defense of this land.
The triangular defense he built on this side of the castle is a defense
against the land, not the sea. The wall is designed to deflect against
stones from armies inland from here, perhaps those of Philippe-Auguste of
France himself.
