Since towers supporting spires are usually square, square-plan spires emerge directly from the tower's walls, but octagonal spires are either built for a pyramidal transition section called a broach at the spire's base, or else freed spaces around the tower's summit for decorative elements like
pinnacles.[1] The former solution is known as a broach spire.[1] Small or short spires are known as spikes, spirelets, or flèches.[1][2]
Etymology
This sense of the word spire is attested in English since the 1590s, spir having been used in
Middle Low German since the 14th century, a form related to the
Old English word spir, meaning a sprout, shoot, or stalk of grass.[3]
The Gothic church spire originated in the 12th century as a simple, four-sided pyramidal structure on top of a church tower. The spire could be constructed of masonry, as at
Salisbury Cathedral, or of wood covered with lead, as at
Notre-Dame de Paris. Gradually, spires became taller, slimmer, and more complex in form. Triangular sections of masonry, called broaches were added to the sides, at an angle to the faces of the tower, as at
St Columba, Cologne. In the 12th and 13th centuries, more ornament was added to the faces of the spires, particularly gabled
dormers over the centres of the faces of the towers, as in the southwest tower of
Chartres Cathedral. Additional vertical ornament, in the form of slender pinnacles in pyramid shapes, were often placed around the spires, to express the transition between the square base and the octagonal spire.[4]
The spires of the late 13th century achieved great height; one example was
Fribourg Cathedral in Switzerland, where the gabled lantern and spire reached a height of 385 feet (117 meters). In England, a tall needle spire was sometimes constructed at the edge of tower, with pinnacles at the other corners. The western spires of
Lichfield Cathedral are an example.[4]
Spires were particularly fragile in the wind, and a number of English Gothic spires collapsed; notably that of
Malmesbury Abbey (1180–1500);
Lincoln Cathedral (which had been the tallest in the world) 1349–1549; and
Chichester Cathedral (1402–1861). The spire of
Salisbury Cathedral, completed in 1320 and 404 feet (123 meters) tall, without the tower, required the addition of buttresses, arches and tie irons to keep it intact. Finally, in 1668 the architect
Christopher Wren designed reinforcing beams which halted the deformation of the structure.[5]
Openwork spires were a notable architectural innovation, beginning with the spire at
Freiburg Minster, in which the pierced stonework was held together by iron cramps. The
openwork spire, represented a radical but logical extension of the Gothic tendency toward a skeletal structure.[6]
Crown spires have a fully exposed structure of arches not unlike the arches of a medieval European
crown. The spire itself is supported by buttress structures.[1]
A needle-spire is a particularly tall and narrow spire emerging from a tower surrounded by a
parapet. In general, the term applies to considerably larger and more refined spires than the name Hertfordshire spike.[1]
A Hertfordshire spike is a type of short spire, needle-spire, or flèche ringed with a parapet and found on church-towers in the
British Isles.[1]
Splay-foot
The roofs of splay-foot spires open out and flatten off at their base, creating
eaves above the tower supporting the spire.[1]
Flèches
The flèche of
Rouen Cathedral (centre), (151 meters), the tallest flèche in France
A flèche (
French: flèche,
lit. 'arrow'[7]) is a name given to spires in
Gothic architecture: in French the word is applied to any spire, but in English it has the technical meaning of a spirelet or spike on the rooftop of a building.[1][2] In particular, the spirelets often built atop the
crossings of major churches in mediaeval
French Gothic architecture are called flèches.[2]
On the ridge of the roof on top of the crossing (the intersection of the
nave and the
transepts) of a church, flèches were typically light, delicate, timber-framed constructions with a metallic sheath of lead or copper.[8] They are often richly decorated with architectural and sculptural embellishments:
tracery,
crockets, and miniature
buttresses serve to adorn the flèche.[8]
The most famous flèche was the Neo-Gothic 19th-century design by
Eugène Viollet-le-Duc for the
Notre-Dame de Paris, 100 feet (30 meters) tall and richly decorated with sculpture. The original flèche of Notre-Dame was built in the 13th century, and removed in 1786, shortly before the
French Revolution. The famous replacement by Viollet-le-Duc with an abundance of sculpture was destroyed in the 2019
Notre-Dame de Paris fire. It will be rebuilt in the same form.
A
pinnacle is a miniature spire that was used both as a decorative and functional element. In early Gothic, as at Notre-Dame de Paris, stone pinnacles were placed atop
flying buttresses, to give them additional weight and stability, and to counterbalance the outward thrust from the
rib vaults of the nave. As an ornament, they were used to break up the horizontal lines, such as parapets and the roofs of towers. In later Gothic, they were sometimes often clustered together into forests of vertical ornament.
Traditional types of spires
Conical stone spires: These are usually found on circular towers and turrets, usually of small diameter.
Masonry spires: These are found on medieval and revival churches and cathedrals, generally with towers that are square in plan. While masonry spires on a tower of small plan may be pyramidal, spires on towers of large plan are generally octagonal. The spire is supported on stone squinches which span the corners of the tower, making an octagonal plan. The spire of
Salisbury Cathedral is of this type and is the tallest masonry spire in the world, remaining substantially intact since the 13th century. Other spires of this sort include the south spire of
Chartres Cathedral, and the spires of
Norwich Cathedral,
Chichester Cathedral and
Oxford Cathedral.
Complex spires: These are stone spires that combine both masonry and openwork elements. Some such spires were constructed in the Gothic style, such as the north spire of Chartres Cathedral. They became increasingly common in
Baroque architecture, and are a feature of
Christopher Wren's churches.
Clad spires: These are constructed with a wooden frame, often standing on a tower of brick or stone construction, but also occurring on wooden towers in countries where wooden buildings are prevalent. They are often clad in metal, such as copper or lead. They may also be tiled or shingled.
Clad spires can take a variety of shapes. These include:
Pyramidal spires, which may be of low profile, rising to a height not much greater than its width, or, more rarely, of high profile.
Rhenish helm: This is a four-sided tower topped with a pyramidal roof. each of the four sides of the roof is
rhomboid in form, with the long diagonal running from the apex of roof to one of the corners of the supporting tower; each side of the tower is thus topped with a gable from whose peak a ridge runs to the apex of the roof.
Broach spires: These are octagonal spires sitting on a square tower, with a section of spire rising from each corner of the tower, and bridging the spaces between the corners and four of the sides.
Bell-shaped spires: These spires, sometimes square in plan, occur mostly in Northern, Alpine and Eastern Europe, where they occur alternately with onion-shaped domes.
Notable spires
The spire of
Burghley House (1555–1587) is an example of a spire on non-religious building.
Salisbury Cathedral's 404 foot (123 m) high spire on the crossing tower has been the tallest church spire in the
British Isles since the collapse of Lincoln's crossing spire in 1548.
St Mary's Church, Stralsund's 495 foot (151 m) high spire made it the
tallest building in the world after the collapse of Lincoln's crossing spire in 1548 until 1569, when
Beauvais Cathedral's tower exceeded it in height. Beauvais's tower collapsed in 1573, after which St Mary's remained the tallest building until 1647, when the spire was destroyed by lightning and subsequently replaced with a lower
Baroque dome (excepting 1569–1573)
Cologne Cathedral's 515 foot (157 m) high spires were built 1248 and 1473, but not completed, and again from 1842, still following faithfully the original plan, until their completions in 1880. The architecture of the spires blends entirely with the tower, making them difficult to separate. The combined tower-spires are 157 meters (515 feet) high.[9] The church is the tallest cathedral anywhere and has the tallest pair of spires.
St Martin's Church, Landshut, spire whose
Brick Gothic tower was finished in 1507, makes it the tallest brick-built church in the world, and the second tallest (unreinforced) brick building anywhere.
Ulm Minster, a Lutheran church in Germany, has the distinction of having the tallest church tower in Europe, at 161.5 metres or 530 feet. The height was deliberately sought to make it slightly higher than the Catholic
Cologne Cathedral.
The organic skeleton of
Antoni Gaudi's spires at the
Sagrada Família in
Barcelona are a blend of Gothic and Gaudi's particular style. Designed and begun by Gaudi in 1884, they are still being completed in the early 21st century.
In
Gothic architecture, where the spire is most commonly used, and particularly in
Gothic cathedrals and churches it symbolised the heavenly aspirations of churches' builders, as well as offering a visual spectacle of extreme height.[4] It also suggested, by its similarity to a spear point, the power and strength of religion.[10]
