A highlight of our tour this morning was the Prague Astronomical Clock. From Wikipedia:
The Orloj is mounted on the southern wall of Old Town Hall in the Old Town Square. The clock mechanism has three main components — the astronomical dial, representing the position of the Sun and Moon in the sky and displaying various astronomical details; statues of various Catholic saints stand on either side of the clock; "The Walk of the Apostles", an hourly show of moving Apostle figures and other sculptures, notably a figure of a skeleton that represents Death, striking the time; and a calendar dial with medallions representing the months. According to local legend, the city will suffer if the clock is neglected and its good operation is placed in jeopardy; a ghost, mounted on the clock, was supposed to nod its head in confirmation. According to the legend, the only hope was represented by a boy born on New Year's night.
The oldest part of the Orloj, the mechanical clock and astronomical dial, dates back to 1410, when it was created by clockmaker Mikuláš of Kadaň and Charles University professor of mathematics and astronomy Jan Šindel. The first recorded mention of the clock was on 9 October 1410. Later, presumably around 1490, the calendar dial was added and the clock facade was decorated with gothic sculptures.
In 1629 or 1659 wooden statues were added, and figures of the Apostles were added after a major repair in 1787–1791. During the next major repair in the years 1865–1866 the golden figure of a crowing rooster was added.
The netting surrounding the structure is in place to protect it from pigeons!
