Gothic Architecture

Gothic architecture is the style of building that prevailed in Catholic Europe and parts of Western Asia from the late 12th century through the 16th century. It is defined by three structural innovations — the pointed arch, the rib vault, and the flying buttress — that together allowed architects to build much taller structures with thinner walls and larger windows than had been possible in the preceding Romanesque tradition. The style was driven by the theological demands of the Catholic Church, which sought buildings in which worshippers could experience divine light filtered through coloured glass, and by the civic pride of growing medieval cities, which competed with one another to erect the tallest and most elaborate cathedrals as expressions of municipal wealth and piety.

## Origin of the term

The term "Gothic" originated as a pejorative. The Italian Renaissance art historian Giorgio Vasari used the term "barbarous German style" to describe medieval pointed-arch buildings in his *Lives of the Artists* (mid-16th century), attributing the style contemptuously to the Goths who had sacked Rome. Vasari's dismissal reflected the Renaissance view that [[classical-architecture|classical architecture]] represented the height of human achievement and that the intervening centuries of pointed arches and vertical stone structure represented a regression. The name "Gothic" stuck, though the identification with the historical Goths has no architectural basis.

## Structural principles and their development

The three structural innovations of Gothic architecture are interconnected: each enables the others, and together they constitute a system for managing the outward thrust of stone vaulting.

### Rib vault

The **rib vault** — a system of diagonal stone ribs crossing at the apex of a ceiling bay — distributes the weight of the vault to specific points rather than along the full length of the wall. By concentrating the load at points, the rib vault allows the wall between those points to be thinned or replaced with windows. The rib vault appeared early in England and Normandy: Durham Cathedral employed rib vaults in its nave, begun in 1093. Sens Cathedral (1135–1140) was the first building to systematically combine rib vaulting, buttresses, and pointed arches, and is considered the first fully Gothic building.

### Pointed arch

The **pointed arch** — an arch formed by two curves meeting at a point rather than a semicircle — is structurally more versatile than the round arch: its angle can be varied to span different widths while maintaining the same height, allowing more flexible floor planning. The pointed arch also directs thrust more steeply downward than a round arch, reducing the outward load on the wall.

### Flying buttress

The **flying buttress**, introduced at Notre-Dame de Paris in the late 12th century, resolves the critical structural problem of Gothic construction: where to put the outward thrust generated by the rib vault. A flying buttress is an arch that bridges from the upper wall of the nave — where the vault's outward push is concentrated — to a heavy masonry pier standing outside the building. By transferring the vault's thrust to an external structure, flying buttresses freed the upper nave walls from structural obligations, allowing them to be filled almost entirely with glass. The result is the characteristic Gothic interior: enormous windows of coloured glass, thin stone walls, and the appearance of a stone skeleton supporting a translucent skin.

In North America, the Gothic Revival arrived in the first half of the 19th century and was quickly adopted for church construction. Protestant denominations — Anglican, Presbyterian, Methodist, Baptist — built Gothic Revival churches across Canadian and American cities throughout the 19th century, applying the pointed arch and stone tracery vocabulary to brick construction at the scale of the local congregation. These church buildings, typically occupying corner sites on the main commercial street or on prominent residential thoroughfares near the downtown core, define the heritage character of secondary market commercial districts as reliably as the neoclassical bank buildings and [[art-deco|art deco]] office blocks that surround them.

### Institutional and civic adoption

Gothic Revival was also applied to institutional and civic buildings: university colleges, law courts, railway stations, and municipal buildings in a number of Canadian cities adopted the Gothic vocabulary as an expression of civic ambition and historical connection. The Supreme Court of Canada in Ottawa (1941) was built in a Gothic Revival style that echoes the Parliament Buildings on the adjacent hill. Victoria University at the University of Toronto (1892) is a Gothic Revival college building.
