Castle building 101

After reading the profile on Jim Bishop I was interested in finding out how he built it. I like to build things and this profile tells of Jim Bishop building what he wants to. Here is a link to a site that gives basic knowledge on how to build a castle. Building a castle appears to take a long time, especially if you are building it by yourself like Bishop. However because it is made of rock it stays the same temp. throughout the entire year which is nice. they also are less likely to be destroyed if a tree falls on them like one made of wood and also likely does not have problems with mold because mold does not eat rocks. so I was curious about castles an that site appears to tell you every thing that you need to build one, awesome.
