One room in the building was devoted to the preservation of ancient archives.

There they showed us no end of aged documents; some were signed by Popes, some by Tilly and other great generals, and one was a letter written and subscribed by Goetz von Berlichingen in Heilbronn in 1519 just after his release from the Square Tower.
This fine old robber-knight was a devoutly and sincerely religious man, hospitable, charitable to the poor, fearless in fight, active, enterprising, and possessed of a large and generous nature.

He had in him a quality of being able to overlook moderate injuries, and being able to forgive and forget mortal ones as soon as he had soundly trounced the authors of them.

He was prompt to take up any poor devil's quarrel and risk his neck to right him.

The common folk held him dear, and his memory is still green in ballad and tradition.
