keep
Let an agent explain castle keeps and their forms, relay development, regional variants and notable examples from architectural history sources, describe function and symbolism, and distinguish keeps from other towers and from later prisons called donjons.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain castle keeps and their forms, relay development, regional variants and notable examples from architectural history sources, describe function and symbolism, and distinguish keeps from other towers and from later prisons called donjons.
The strongest and most secure tower of a medieval castle, serving as a residence, a stronghold of last resort and a symbol of lordship, known in French as donjon and in German as Bergfried for the tall tower form, built as rectangular great towers such as the Tower of London, round towers, shell keeps enclosing a courtyard on a motte, and regional forms such as the Volynskaya towers of the Ruthenian lands; keeps developed from the tenth century, declined with gunpowder artillery, and survive as ruins and museums.
What it is for: Defence, residence and display in castles.
It can be explain forms and function; relay development and variants; describe notable examples; distinguish from other towers.

What the second pass must settle
