Wenceslas I was crowned with his wife Kunhuty in 1228. The crown is made of four gold plates set with 91 polished rubies, emeralds and sapphires, and 20 pearls, with two arches supporting a monde and cross reputed to contain a thorn from the Crown of Thorns.
Kept in St. Vitus's Cathedral, Prague, it is one of the oldest and finest examples of the mediaeval Lily crown to have survived.
