Bathhouse
In Medieval Europe most people who lived in towns went to bathhouses to bathe.  The medical book Secreta Secretorum has a chapter on bathing. It said winter and spring were good times to bathe but that people should not bathe in summer.  By 1200 AD, there were 32 bathhouses in Paris.  Bathhouses were often right next to the town bakery so the heat from the ovens could make the water hot.  In Germany in the 1400s, some people ate meals in baths.  Sometimes bathhouses were brothels in disguise.  When the disease syphilis reached Europe, bathhouses became less popular there.
