The Habsburg Emperor Rudolf II left a deep mark in Czech history. Various legends and myths surround the 16th century ruler who made Prague his imperial seat and whose diverse interests made the city a centre of Renaissance arts and sciences. One monument from his time is hidden beneath the surface of the earth – a water tunnel carved deep into the rock of one of Prague’s hills.
