Today is the 650th anniversary of Charles Bridge. The foundation stone was laid at 5:31am on July 9, 1357 with the help of king Charles IV. He consulted his astrologers and the date and time were chosen so that the odd numbers that ascend and descend on the scale of 1 – 9 would form the palindrome 135797531.
