The openwork spire, according to Robert Bork, represents a "radical but logical extension of the Gothic tendency towards skeletal structure." The organic skeleton of Antoni Gaudi's phenomenal spires at the Sagrada Família in Barcelona represent an outgrowth of this Gothic tendency. Designed and begun by Gaudi in 1884, they were not completed until the 20th century. In England, "spire" immediately brings to mind Salisbury Cathedral. Its 403-foot (123-m) spire, built between 1320 and 1380,

Because most of the cathedral was built in only 38 years, it has a single consistent architectural style, Early English Gothic. Although the spire is the cathedral's most impressive feature, it has proved to be troublesome. Together with the tower, it added 6,397 tons (6,500 tonnes) to the weight of the building. Without the addition of buttresses, bracing arches and anchor irons over the succeeding centuries, it would have suffered the fate of spires on other great ecclesiastical buildings (such as Malmesbury Abbey, 1180 to 1500; Lincoln Cathedral, 1311 to 1549;
