pražský most

On this day in 1357 on the banks of the Vltava in Prague, Holy Roman Emperor Charles IV (Charles of Luxembourg born Wenceslaus / Václav / Wenzel) helped lay the cornerstone of his namesake bridge—Karlův most (see previously)—construction completed nearly a half-century later. According to local lore—strongly informed by the emperor’s belief in numerology and the significance of auspicious dates—the foundation stone was laid at precisely at thirty-one past five o’clock in the morning to form a palindrome and numerical span—1357 9/VII V 31. For over four-hundred years the only river crossing and linking the castle to the Old Town market, this connection made the city an important trade hub between eastern and western Europe.
