Two architectural styles were significant during the Middle Ages - the Romanesque style and the Gothic style.
With the introduction of the pointed (Gothic) arch, it became possible to build incredibly tall and slender buildings. Buttresses and flying buttresses, could transfer the heavy loads of the masonry to the ground, allowing the windows to reach previously unseen dimensions.
In Gothic cathedrals daylight enters through colorful stained-glass windows creating a divine ambience. The Gothic style served as an inspiration for later style periods, such as the Historicistic style and the Gothic Revival in the 19th century, where architects were occupied with recreating the divine light from the gothic windows.
