After Wenceslaus it was the seat of Sigismund of Luxembourg, Albert II of Habsburg, Ladislaus the Posthumous, George of Poděbrady and Vladislaus Jagiellon, who moved the seat of the kings back to Prague Castle.[2] According to the Municipal House, the King's Court served as the royal seat from 1383 to 1484.[2] Under Wenceslaus IV some partial additions to the decoration of the Old Town Bridge Tower were also made.[3]
