World Astronomical Clocks
Italian Cremona is the largest astronomical clocks in the third tallest brickwork Tower in the world. This tower was built in the 13th century, but locals say that construction began in the 8th century. Archaeologists have discovered ancient Roman foundations under the tower. The makers of watches (1583 – 1588) are father and son – Francesco and Giovan Divizioli. The face reflects the passage of the Sun through the signs of the zodiac. The construction of astronomical clocks requires art skills, knowledge of mechanics and quite a bit of astronomical knowledge.
The most popular tourist attraction is the The Zytglogge Tower in Bern. The tower itself was built in the 13rd century, and the clock was installed in the 15th. Created in the form of the astrolabe dial-navigation tool that defines the position of the stars, Sun, Moon and the planets.
These 14-century clocks were built both inside and outside the building. Interior reflects a model of the universe. Against the background the stars and the Sun moves in a circle. The 24 hour clock face has a clock from one to twelve in the afternoon and from one to twelve after midnight. The same mechanism drives the watch movement outside the Cathedral.
The clock is set in the main square of the city. They are reconstructed once every hundred years. Czech Republic was severely damaged at the end of World War II in 1945. The shot by Germans clocks, they are kept in the local museum.
In the Cathedral of Strasbourg there are three astronomical clocks. First clocks were established in 1352, and worked for two hundred years until they have improved in 1547, having served until 1788. In 1838, the last clocks were displayed, they work to this day.
Two Knights at the top mark, and astronomical clock dials show the phases of the Moon, where and when the sun go down, and more. The third dial on top of the calendar. Through it, our ancestors had to calculate the dates of religious holidays.
Prague Orloj is a medieval astronomical clock located in Prague. These watches were created in 1410. The Centre of the dial shows the position of the Sun and the moon. There are also mechanical figures of Apostles, which move every hour, also has a dial with the months of the year.
In 1930, astronomer and clock-maker Louis Zimmer (1888-1970) built the Jubilee (or Centenary) Clock which is displayed on the front of the tower. The clocks consist of 12 clocks encircling a central one with 57 dials. These clocks showed time in all continents, phases of the moons, times of tides and many other periodic phenomena. It was decided to place this new design in the old tower, which had to be reconstructed for this. In honor of the astronomer they renamed the tower the Zimmer tower.
The cathedral and bell tower of Messina had to be rebuilt more than once. The cathedral had been entirely rebuilt in 1919 and 1920, following the 1908 earthquake, and again in 1943. The current campanile was built in 1933 by the Ungerer Company of Strasbourg.
