The Bohemian crown jewels, also called the Czech crown jewels, include the Crown of Saint Wenceslas, the royal orb and sceptre, the coronation vestments of the Kings of Bohemia, the gold reliquary cross, and St. Wenceslas' sword. They were originally held in Prague and Karlštejn Castle, designed in the 14th century by Matthias of Arras. Since 1791 they have been stored in St. Vitus Cathedral at Prague Castle. Reproductions of the jewels are permanently exhibited in the historical exposition at the former royal palace in the castle. The crown was made for the coronation of Charles IV in 1347, making it the fourth oldest in Europe.

The crown of Saint Wenceslas is a crown forming part of the Bohemian crown jewels, made in 1346. Charles IV, king of Bohemia and Holy Roman Emperor, 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 deposited in St. Vitus Cathedral, however, it was later transferred to Karlštejn Castle. It was used for the last time for the coronation of Ferdinand V in 1836.
