After three days spent in Munich-Germany, we took the highway to Prague on board of a bus. We enjoyed the ride on a highway similar to those of the U.S.. It was surprising to see the influence of the United states in Central Europe. However, once we arrived in Prague, we discovered an architectural inheritance reflecting the cultural history of Prague and it cohanitance with modernity. We also visited one of the heritage, a bunker, of the Ex-Soviet Union located in the basement of an hotel. It was used during the cold war to fight espionage and a safe place to be in case of nuclear attack. Surprisingly, some artifacts were found and maintained as wetness of this past. It was an interesting evening of diving in the past of the Tchec Republic.
