Astronomy in Prague

Yesterday we wandered through the old city of Prague and came upon the Klementinum, an 18th century Jesuit university. They had replicas of the instruments used in Prague by Tycho Brahe and Kepler and recreations in place in the observing tower of slightly later similar instruments. Most interesting in the observing tower was the system used to measure local noon at 19th century and give a signal to the town clocks. We visited Tycho’s grave but not the oval chapel where Kepler supposedly got the idea of elipses—it is closed for renovation.
