Castle building and constant castle repair—like any war effort—ate
up the resources of the land, both in materials and labor (see Documents
15–19). The very nature of the castle almost guarantees that it shall be
destroyed—either in war or by official decree. Siege warfare required the
breaching of castle walls and the destruction of towers. As rulers brought
feudal holdings under a central government, they could not afford to
have castles in the hands of possible rivals or unruly subjects. A castle is
said to be “slighted” when it is officially destroyed. Over time, nature also
adds to the castle’s disintegration, recapturing its own with vines and underbrush
and even trees. To visit a castle is to see broken walls, roofless
halls, and sometimes only stone foundations and earthworks. When a
castle seems at first glance to be intact, we can be certain it has been rebuilt.
We must turn to archeology, to historical archives, and to art history
for information. Even then we need an active imagination to study
castles.
