Crown of Saint Wenceslas
The Crown of Saint Wenceslas is a crown forming part of the Bohemian Crown Jewels, made in 1347. The eleventh king of Bohemia and Holy Roman Emperor Charles IV, from the House of Luxembourg, had it made for his coronation, dedicating it to the first patron saint of the country St. Wenceslas and bequeathed it as a state crown for the coronation of (future) Bohemian kings. On the orders of Charles IV the new royal crown was permanently deposited in Karlštejn Castle near Prague). It was used for the last time for the coronation of Ferdinand V in 1836.
Unlike many other European royal treasures, the St. Wenceslas Crown is not displayed publicly, and only a replica is shown. Along with the other Bohemian crown jewels, it is kept in a chamber within St. Vitus Cathedral accessible by a door in the St. Wenceslas Chapel. The exact location of the chamber is not known to the general public. The entrance to the jewels is locked by seven locks whose keys are held by the President of the Czech Republic, Chair of the Chamber of Deputies of the Parliament, Chair of the Senate of the Parliament, the Prime Minister, Mayor of Prague, Archbishop of Prague and the Dean of Metropolitan Capitule in Prague. The jewels are only taken from the chamber and displayed for periods of several days on notable occasions approximately once every five years. The crown was exhibited in May 2016 to mark the 700th anniversary of the birth of Charles IV, and in May 2013, celebrating the inauguration of a new Czech president.
An old Czech legend says that any usurper who places the crown on his head is doomed to die within a year, as the Crown is the personal property of St. Wenceslas and may only be worn by a rightful Bohemian king during his coronation. During World War II, Reinhard Heydrich, the Deputy Protector of Bohemia and Moravia, is said to have secretly "crowned" himself while inspecting St. Vitus' Cathedral, and was assassinated less than a year later by the Czech resistance. Although there is no evidence proving that Heydrich did so, the legend is widely believed.
