Speyer Cathedral

← Encyclopedia

Speyer Cathedral — formally the Cathedral Basilica of the Assumption and Saint Stephen — is the imperial church begun on the Upper Rhine around 1030 by Conrad II, first ruler of the Salian dynasty, and remains the largest surviving Romanesque church in the world. It stands at the western edge of the city of Speyer, in present-day Rhineland-Palatinate, and was inscribed as a UNESCO World Heritage Site in 1981.

Conrad conceived the building on a scale meant to declare something: that the empire he had inherited was not only a political order but a sacred one, answerable to God and worthy of a house as vast as a Roman basilica. Work continued under his son Henry III and grandson Henry IV, who enlarged and vaulted the structure into the form that survives — a long stone nave rising to groin vaults, a tower at each of the four corners, and a great octagonal dome over the crossing. The east end sits above a crypt of pale columns, among the most extensive Romanesque crypts in Europe, and it is there that the dynasty chose to be buried.

The cathedral’s deepest significance is dynastic and liturgical rather than esoteric. Eight emperors and kings of the medieval Empire lie in its crypt, including the four Salian rulers, and the church functioned for centuries as the imperial necropolis of the German lands — the place where the sacral character of kingship was given architectural form. Coronations, royal funerals, and the ordinary round of the Mass were held within walls built to make the claim that earthly rule descended from a heavenly source. The building was understood, in the theology of its founders, as an image of the heavenly Jerusalem set down in stone.

The structure has not come down untouched. It was damaged in the wars of the seventeenth century, when French troops burned the western portion and disturbed the imperial tombs, and the western block was rebuilt in the nineteenth century; the nineteenth century also added, then later removed, a heavy program of interior painting, so that the interior seen today is closer to the bare Romanesque stone the Salians knew. The crypt and the main body of the eleventh-century church remain largely as built.

Its interest lies in what a Romanesque cathedral was meant to do: to stand as a permanent argument, in proportion and mass, that the visible order of rulers and the invisible order of God were one fabric. The argument was made in stone, and the stone is still standing.
