Arching above a side aisle roof, flying buttresses support the main vault of St. Mary's Church, in Lübeck, Germany.. The flying buttress (arc-boutant, arch buttress) is a specific form of buttress composed of an arch that extends from the upper portion of a wall to a pier of great mass, in order to convey to the ground the lateral forces that push a wall outwards, which are forces that arise ...
The flying buttress was an essential feature of High Gothic architecture; the great height and large upper windows would have been impossible without them. Buttresses with arches apart from the walls had existed in earlier periods, but they were generally small, close to the walls, and were often hidden by the outer architecture.
In these the buttresses run up, forming a sort of square turret, and crowned with a pyramidal cap, very much like those of the next period, the Early English.

Generally, in Gothic masterpieces, the clerestory is divided into bays by the vaulting shafts that continue the same tall columns that form the arcade separating the aisles from ...
However, they also noticed that the local Muslim architecture deployed the much more flexible two-point or Gothic arch. The semi-circular arch was heavy and, in spite of this, resulted in weaknesses when two barrel vaults intersected. The 'gothic arch' on the other hand was stronger and could be used to make for wider unsupported spaces.
