The rosette window in the west portal of St. Vitus Cathedral at Prague Castle. The cathedral’s name is shortened; the full name is the Cathedral of St. Vitus, Wenceslas, and Adalbert. In 929, the first rotunda was built on this site by the order of Prince Wenceslas (later St. Wenceslas) . The rotunda was later demolished and replaced with a basilica in 1060.
The foundation stone of today’s cathedral was laid on November 21, 1344. It was laid by King John of Luxembourg in the presence of his son Charles IV. The cathedral was consecrated nearly 600 years later in 1929 with the rosette having been created only a few years before. Its theme is the creation of the world.
