The Bohemian Crown Jewels of Prague are famous not only they are precious but also for their prominence in the history of Prague. They have been stored in St. Vitus Cathedral at Prague Castle. These are displayed only on rare occasions and are under heavy protection.
The crowning glory of the jewels is, of course, the St Wenceslas Crown. It is named after the patron saint of the Czech lands, Saint Wenceslas from the Přemyslids dynasty of Bohemia. An ancient Czech legend says that offender of the Czech lands placing the crown on his head is certified of death within a year.
