Attached to Monplaisir Palace is the Bathouse Block. This complex of buildings and halls were built over nearly 150 years through 1866. The Guest Quarters provided overnight accommodations for the emperor’s guests while the Assembly Hall was the venue for entertaining them during formal dinners. Peter I enjoyed relaxing in the Suds Bath. The empress consort of Alexander II of Russia commissioned the Bathhouse. Inside was a steam room plus warm and cold water pools.
