Gothic architecture towers on the front is the norm. In England, Germany and Scandinavia this is often the arrangement, but an English cathedral may also be surmounted by an enormous tower at the crossing. Smaller churches usually have just one tower, but this may also be the case at larger buildings, such as Salisbury Cathedral or Ulm Minster in Ulm, Germany, completed in 1890 and possessing the tallest spire in the world, slightly exceeding that of Lincoln Cathedral, the tallest spire that was actually completed during the medieval period, at . The exteriors and interiors of Gothic cathedrals, particularly in France, were
Spire (mollusc) the protoconch (also called the nuclear whorls or the larval shell), and most of the subsequent teleoconch whorls (also called the postnuclear whorls), which gradually increase in area as they are formed. Thus the spire in most gastropods is pointed, the tip being known as the "apex". The word "spire" is used, in an analogy to a church spire or rock spire, a high, thin, pinnacle. The "spire angle" is the angle, as seen from the apex, at which a spire increases in area. It is an angle formed by imaginary lines tangent to the spire. Some gastropod shells have
