The Czech city of Karlovy Vary is a true resort spa town that is famous for the hot spring water with “curative” powers. There is a special cup from which you are supposed to drink the water daily. The temperature is about 72 degrees CENTIGRADE. Obviously, from the sediment in this bowl, the water contains many minerals, and it appears that sulphur may be in abundance!
Prague was hard-hit by the Nazi invaders of World War II because of the high percentage of Jews who lived there. These walls (and there are MANY more) show the names of those who never returned from concentration camps. The red name indicates the surname, followed by the given names of those who were lost. A somber sight, indeed.
