Next one on the list is the #beautiful #Burg #Reichenstein (“rich stone”), overseeing the #Rhine #River valley with its lavish #wineyards. This #castle is part of the #UNESCO World Heritage effort – it was built around 1100 AD, though it’s still unclear by whom. All that is known about its history is that throughout the centuries it was housed and used to collect tolls from travelers and merchants passing through by various high ranking families until it was finally given to the #archbishop of Mainz.
