Exquisite! A very beutiful MOC. There is a TON of detail to it, he included a well, implemented that lamp design we discussed here a little while ago, and used burps for some of the rock base. Look at the sword holder next to the door in this
picture and the neat telescope on the same landing.
The amount of mottling is perfect, I love the use of tudor sections, and the butresses are implemented well.
I looked up the meaning of Col du Mont and it basically means mountian pass, so this castle is a tower perhaps guarding a pass between mountains. It looks to be about the right size for that.
It also helps that it's a crusader fortress... I really like this one Bruce, thanks for posting about it!
