Towers and spires

Towers, spires and flèches were an important feature of Gothic churches. They presented a dramatic spectacle of great height, helped make their churches the tallest and most visible buildings in their city, and symbolised the aspirations of their builders toward heaven. They also had a practical purpose; they often served as bell towers supporting belfries, whose bells told the time by announcing religious services, warned of fire or enemy attack, and celebrated special occasions like military victories and coronations. Sometimes the bell tower is built separate from a church; the best-known example of this is the Leaning Tower of Pisa.

The towers of cathedrals were usually the last part of the structure to be built. Since cathedral construction usually took many years, and was extremely expensive, by the time the tower were to be built public enthusiasm waned, and tastes changed. Many projected towers were never built, or were built in different styles than other parts of the cathedral, or with different styles on each level of the tower. At Chartres Cathedral, the south tower was built in the 12th century, in the simpler Early Gothic, while the north tower is the more highly decorated Flamboyant style. Chartres would have been even more exuberant if the second plan had been followed; it called for seven towers around the transept and sanctuary.

In the Île-de-France, cathedral towers followed the Romanesque tradition of two identical towers, one on either side of the portals. The west front of the Saint-Denis, became the model for the early Gothic cathedrals and High Gothic cathedrals in northern France, including Notre-Dame de Paris, Reims Cathedral, and Amiens Cathedral.

The early and High Gothic Laon Cathedral has a square lantern tower over the crossing of the transept; two towers on the western front; and two towers on the ends of the transepts. Laon's towers, with the exception of the central tower, are built with two stacked vaulted chambers pierced by lancet openings. The two western towers contain life-size stone statues of sixteen oxen in their upper arcades, said to honour the animals who hauled the stone during the cathedral's construction.

In Normandy, cathedrals and major churches often had multiple towers, built over the centuries; the Abbaye aux Hommes (begun 1066), Caen has nine towers and spires, placed on the façade, the transepts, and the centre. A lantern tower was often placed the centre of the nave, at the meeting point with the transept, to give light to the church below.

In later periods of Gothic, pointed needle-like spires were often added to the towers, giving them much greater height. A variation of the spire was the flèche, a slender, spear-like spire, which was usually placed on the transept where it crossed the nave. They were often made of wood covered with lead or other metal. They sometimes had open frames, and were decorated with sculpture. Amiens Cathedral has a flèche. The most famous example was that of Notre-Dame de Paris. The original flèche of Notre-Dame was built on the crossing of the transept in the middle of the 13th century, and housed five bells. It was removed in 1786 during a program to modernize the cathedral, but was put back in a new form designed by Eugène Viollet-le-Duc. The new flèche, of wood covered with lead, was decorated with statues of the Apostles; the figure of St Thomas resembled Viollet-le-Duc. The flèche was destroyed in the 2019 fire, but is being restored in the same design.

In English Gothic, the major tower was often placed at the crossing of the transept and nave, and was much higher than the other. The most famous example is the tower of Salisbury Cathedral, completed in 1320 by William of Farleigh. It was a remarkable feat of construction, since it was built upon the pillars of the much earlier church. A crossing tower was constructed at Canterbury Cathedral in 1493–1501 by John Wastell, who had previously worked on King's College at Cambridge. It was finished by Henry Yevele, who also built the present nave of Canterbury. The new central tower at Wells Cathedral caused a problem; it was too heavy for the original structure. An unusual double arch had to be constructed in the centre of the crossing to give the tower the extra support it needed.

England's Gothic parish churches and collegiate churches generally have a single western tower. A number of the finest churches have masonry spires, with those of St James Church, Louth; St Wulfram's Church, Grantham; St Mary Redcliffe in Bristol; and Coventry Cathedral. These spires all exceed 85 m (280 ft) in height.

Westminster Abbey's crossing tower has for centuries remained unbuilt, and numerous architects have proposed various ways of completing it since the 1250s, when work began on the tower under Henry III. A century and half later, an octagonal roof lantern resembling that of Ely Cathedral was installed instead, which was then demolished in the 16th century. Construction began again in 1724 to the design of Nicholas Hawksmoor, after first Christopher Wren had proposed a design in 1710, but stopped again in 1727. The crossing remains covered by the stub of the lantern and a 'temporary' roof.

Later Gothic towers in Central Europe often followed the French model, but added even denser decorative tracery. Cologne Cathedral had been started in the 13th century, following the plan of Amiens Cathedral, but only the apse and the base of one tower were finished in the Gothic period. The original plans were conserved and rediscovered in 1817, and the building was completed in the 19th century following the origin design. It has two spectacularly ornamented towers, covered with arches, gables, pinnacles and openwork spires pointing upwards. The tower of Ulm Minster has a similar history, begun in 1377, stopped in 1543, and not completed until the 19th century.

Regional variants of Gothic towers appeared in Spain and Italy. Burgos Cathedral was inspired by Northern Europe. It has an exceptional cluster of openwork spires, towers, and pinnacles, drenched with ornament. It was begun in 1444 by a German architect, Juan de Colonia (John of Cologne) and eventually completed by a central tower (1540) built by his grandson.

In Italy the towers were sometimes separate from the cathedral; and the architects usually kept their distance from the Northern European style. the leaning tower of Pisa Cathedral, built between 1173 and 1372, is the best-known example. The Campanile of Florence Cathedral was built by Giotto in the Florentine Gothic style, decorated with encrustations of polychrome marble. It was originally designed to have a spire.
