The remains of the Haut-Koenigsbourg castle were entrusted to the Thierstein family in 1479, who rebuilt it and adapted it to the artillery. Their coat of arms is visible above the access door to the interior courtyard. In Old German, their name comes from thier which means hind, and stein, stone. The Thierstein coat of arms does indeed represent a doe on a green and rocky terrace. The counts of Thierstein sometimes amused themselves by changing the animal present on their blazon: sometimes a dog, sometimes a wolf, or a sheep. It is always placed on a stone so that the two associated figures would form a talking rebus.
