This particular Cathedral is of a gothic style is located in Paris, on a small island in the Seine River. It is unknown who designed this Cathedral, but it was designed for in a 12th century cathedral building competition. It was built from 1163 to 1250, under the reign of Louis VII.
During construction it was determined that the walls and windows would be built higher, which caused unforeseen problems. The windows were so high up that light barely shone through them and there was the added problem of greater wind speeds and pressure. To solve this problem, the first ever flying buttresses were introduced.
In 1250, Jean de Chelles decided to remove the plain walls of the Cathedral and replace them with stained glass walls. One of his greatest accomplishments was the rose of the north window. It rises 43 by 57 feet, with 1,300 square feet of geometrically cut pieces of glass that has lasted over 700 years. The precision of the stone cutters were so great that in a hundred years only 20 attempts were made to build windows of such magnitude, but none could be greater than that of Notre Dame. The rose window symbolizes events in the Bible. It consists of the Mary in the center with the infant Jesus. Acting as a frame are pictures of 64 kings and priests.
Among the significant events, Henri VI of England was crowned here in 1430.
