Prague: Charles Bridge celebrates 650th anniversary

numerological basis:

On that day, 650 years ago, several odd numbers came into alignment: The year was 1357. It was also the 9th day of the seventh month. The first stone was placed at exactly 5:31. As a result, the sequence of numbers occurs as 1, 3, 5, 7, 9, 7, 5, 3, 1. Moreover, the timing also had significant astrological importance, as all the known planets were on the horizon while the Sun, Mercury and Saturn were mutually conjoined, disrupting the latter planet’s unfavorable influence.

Fancy! If the construction of the metro extension to Ruzyne was half as well organized, it might already be built by now.
