To build, design, or modify a structure to resemble a castle or to add castle-like features such as crenellations or towers.
From Latin 'castellatus' (made into a fort), derived from 'castellum' (castle). The '-ate' verb suffix indicates the action of making or creating something with the specified quality.
Wealthy medieval nobles would 'castellate' their homes—adding fake battlements and towers even when there was no military threat—because a castle-looking house basically screamed 'I'm important!' It was medieval architectural cosplay!
