Brandenburg. Das Museum setzt sich mit der Sozial- und Technikgeschichte des alten Glasmacher-Ortes auseinander.
Eine Ausstellung über den Erfinder der Thermoskanne Reinhold Burger ist zu besichtigen. Im Dorf selbst haben sich
zahlreiche Handwerker und Gewerbetreibende niedergelassen, denen über die Schulter geschaut bzw. mitgemacht
werden kann.
