Prague’s medieval Old Town Square was founded in the 10th century and served as a market place at the crossing of the European merchants’ trade roads. This square has also served witness to significant and tragic events in the country’s history. The square has been used for executions, parades and many important political events and demonstrations.
One of the most notable executions is commemorated at the base of the famous astronomical clock, where you will see 27 white crosses and the year 1621 inlaid into the cobblestones. These markings memorialize the spot where 27 Protestant noble rebel leaders were beheaded after rebelling against the Catholic emperor.
