Gvardeyskoye (Russian: Гварде́йское, Lithuanian: Miulhauzenas) is a rural locality (a settlement) in Bagrationovsky District of Kaliningrad Oblast, Russia, located approximately 10 kilometers (6.2 mi) north of Bagrationovsk, the administrative center of the district, and 25 kilometers (16 mi) south of Kaliningrad, the administrative center of the oblast. It was previously known in German as Mühlhausen (Kreis Preußisch Eylau).
It was founded by the Teutonic Knights in the Old Prussian region of Natangia as a location of a mill (mühle means a mill) and a church, first mentioned in 1372. IT was given as a pawn by the Order to Daniel von Kunheim in 1474. The laird Georg von Kunheim, a student at Wittenberg, married Martin Luther's youngest daughter Margarethe Luther in 1555; she died in Mühlhausen in 1570. Two paintings of Luther and his wife Katharina von Bora by Lucas Cranach existed at the church up to 1945, as well as the original summons of Martin Luther by Emperor Charles V to the Diet of Worms and an original letter, written by Luther.
