The jewel of the collections at this 1665 mansion, a former hospital near Sint Janskerk, is a gold chalice that Countess Jacqueline of Bavaria presented to the Society of Archers in 1465. Its whereabouts were unknown for over a century before it was recovered in the Town Hall's attic and brought here. There are colorful guild relics, antique furniture, antique pipes and plateel, a colorful pottery that is Gouda's answer to Delftware, and a terra-cotta plaque whose Latin inscription proclaims that the humanist Erasmus may have been born in Rotterdam but was conceived in Gouda. There's limited wheelchair access.
