full_context: Document 1: Vyšehrad: Vyšehrad (Czech for "upper castle") is a historic fort located in the city of Prague, Czech Republic, just over 3 km southeast of Prague Castle, on the right bank of the Vltava River. It was built probably in the 10th century. Situated within the fort is the Basilica of St. Peter and St. Paul, as well as the Vyšehrad Cemetery, containing the remains of many famous people from Czech history, among them Antonín Dvořák, Bedřich Smetana, Karel Čapek, and Alphonse Mucha. It also contains Prague's oldest Rotunda of St. Martin from the 11th century.
Document 2: Astronomical clock: The first clock was built between 1352 and 1354 and stopped working sometime at the beginning of the 16th century. A second clock was then built by Herlin, Conrad Dasypodius, the Habrecht brothers, and others, between 1547 and 1574.

Document 4: Embassy of Sweden, Prague: The Swedish Embassy to the Czech Republic is located on Úvoz street, in Hradčany, the castle region of Prague. It is close to the Strahov Monastery. The embassy has a great view of the rest of Prague because it is located up on the hill. A pedestrian path, named after Swedish diplomat Raoul Wallenberg, who saved thousands of Jews from the Holocaust, leads from embassy up to the Petrin Hill.
Document 5: Time: The most precise timekeeping device of the ancient world was the water clock, or clepsydra, one of which was found in the tomb of Egyptian pharaoh Amenhotep I (1525–1504 BC). They could be used to measure the hours even at night, but required manual upkeep to replenish the flow of water. The Ancient Greeks and the people from Chaldea (southeastern Mesopotamia) regularly maintained timekeeping records as an essential part of their astronomical observations. Arab inventors and engineers in particular made improvements on the use of water clocks up to the Middle Ages. In the 11th century, Chinese inventors and engineers invented the first mechanical clocks driven by an escapement mechanism.
Document 6: Jan Šindel: Jan Šindel was born in the Bohemian town Hradec Králové probably in the 1370s. As a young man he came to Prague to study at Charles University. In 1395 or 1399 he became the Master of Arts at Prague University. In 1406 he worked at the parish school of the St. Nicolas Church in the Lesser Town of Prague. Later he worked as a teacher of mathematics in Vienna, where he also studied medicine. Then he came back to Prague and became the professor of astronomy at Charles University, where he became Doctor of Medicine and rector of the university in 1410.
Document 7: Rosenburg: Rosenburg is a castle in the municipality Rosenburg-Mold, Lower Austria, Austria. Rosenburg is on a cliff above the valley of the River Kamp at an elevation of above sea level. It is one of Austria's most visited Renaissance castles. It is situated in the middle of a nature reserve - the Naturpark Kamptal - which adds to its appeal. There are various castles and fortifications in Austria and Germany that bear the name "Rosenburg", but if people use the term without further specifications, it may be understood that they refer to this site in Lower Austria. The well-known Austrian folk song "Es liegt ein Schloss in Österreich" ("There is a castle in Austria") is often assumed to refer to the Rosenburg.
Document 8: Computer: Many mechanical aids to calculation and measurement were constructed for astronomical and navigation use. The planisphere was a star chart invented by Abū Rayhān al-Bīrūnī in the early 11th century. The astrolabe was invented in the Hellenistic world in either the 1st or 2nd centuries BC and is often attributed to Hipparchus. A combination of the planisphere and dioptra, the astrolabe was effectively an analog computer capable of working out several different kinds of problems in spherical astronomy. An astrolabe incorporating a mechanical calendar computer and gear-wheels was invented by Abi Bakr of Isfahan, Persia in 1235. Abū Rayhān al-Bīrūnī invented the first mechanical geared lunisolar calendar astrolabe, an early fixed-wired knowledge processing machine with a gear train and gear-wheels, circa 1000 AD.

Vlastislav Hofman built the entrance pavilions of Ďáblice Cemetery in 1912–1914, Josef Chochol designed several residential houses under Vyšehrad. A Cubist streetlamp has also been preserved near the Wenceslas Square, designed by Emil Králíček in 1912, who also built the Diamond House in the New Town of Prague around 1913.
