Best i know it was s mixed bag, dependent on numerous factors, the exact purpose of the castle, the wealth of the laird, the availability of materials. If it was a defence structure only, then it was unlikely to have been rendered,/washed/painted. As time went on, these weren't just defensive though, they were homes to nobility. So traditionally the castles were rendered/washed in some shade. Often a bright shade as they wanted to be known in the area and to leave no doubt where the centre of power was, who was the richest etc. Nowadays in Scotland probably most look like this but there are still examples, Craigievar is Pink for one... there's a lot to it all. Quite interesting, the evolution of castles through history.
Hi there! Looks like you linked to a Lemmy community using a URL instead of its name, which doesn't work well for people on different instances. Try fixing it like this: !castles@lemm.ee
