Did you know??

The numerical palindrome 135797531 carved on to the Old Town Bridge Tower at the east end of the bridge is far from random. This sequence, which reads the same backward and forward, refers to the exact time and date of the placement of the bridge’s foundation stone, determined by royal astrologers as an auspicious time. Work began on the 9th of July 1357 at 5.31 AM. Medieval beliefs attributed a magical power to odd numbers and arranged them in a particular way to create a pyramidal pattern symbolic of power.
