Pat,
Re: cathedral construction.
Yes, cathedrals were built over a period of centuries. But people were using
them during that time and would notice cracks other signs of structural
weakness. Was there an example of someone taking a _ruined_ cathedral and
adding further construction to it? Or a castle? Chip was specifying
_ruins_.
re: towers
>From what I've read, towers were just the first step of castle construction,
before the owning noble could afford a full-sized castle. Therefore, they
tended to be placed in defensible locations, i.e., on top of something,
thereby sticking out like a sore thumb. Not like Grendel's lair, hidden
under the ocean (if I remember correctly).

Not a STEALTH skill, a PERSUASION skill.
