Gothic cathedrals
In 1127 Suger decided to rebuild the great abbey Church of Saint-Denis. He began by changing the "West Front" or facade. This side of the church was about 200 years old and had only one small door. Suger planned for three big doors like the arches on the Arch of Constantine in Rome. These large entrances let in all the crowds on special Holy Days. The facade also had a big round window in the centre, called a rose window, which was the first one in France.
