Two of Prague's most-visible landmarks are in Žižkov: the National Monument, with its giant statue of Jan Žižka on horseback (by Bohumil Kafka, it is the third largest equestrian statue in the world); and the 216 meter-high Žižkov Television Tower, Prague's tallest structure. The very large Olšany Cemetery also takes up much of the district. The adjacent New Jewish Cemetery, one of two historic Jewish burial places in the district (the other being the Žižkov Cemetery next to the Žižkov Tower), contains the grave of Czech-German writer Franz Kafka.
