when was st georges chapel at windsor castle built
St George's Chapel, Windsor Castle In 1348, King Edward III founded two new religious colleges: St Stephen's at Westminster and St George's at Windsor. The new college at Windsor was attached to the Chapel of St Edward the Confessor which had been constructed by Henry III in the early thirteenth century. The chapel was then rededicated to the Blessed Virgin Mary, Edward the Confessor and George the Martyr. Edward III also built the Aerary Porch in 1353–54. It was used as the entrance to the new college.
