when was the astronomical clock in prague built
Prague astronomical clock The oldest part of the Orloj, the mechanical clock and astronomical dial, dates back to 1410 when it was made by clockmaker Mikuláš of Kadaň and Jan Šindel, then later a professor of mathematics and astronomy at Charles University. The first recorded mention of the clock was on 9 October 1410.[2] Later, presumably around 1490, the calendar dial was added and the clock facade was decorated with gothic sculptures.
List of World Heritage Sites in the Czech Republic With the dissolution of Czechoslovakia on January 1, 1993, the country was split into the Czech Republic and Slovakia. Either party sought to honour treaty obligations signed by Czechoslovakia including the World Heritage convention. The Czech Republic officially succeeded the convention on March 26, 1993 (five days before Slovakia), inheriting these three sites. More sites were added in the years 1994, 1995, 1996, 1998, 1999, 2000, 2001 and 2003. As of July 2014, the Czech Republic has 12 total sites inscribed on the list. All of these sites are of the cultural type and none of them is shared with other countries.[3]
