Begun in 1030 under Konrad II, with the east end and high vault of 1090xe2x80x931103, the imposing triple-aisled vaulted basilica of red sandstone is the "culmination of a design which was extremely influential in the subsequent development of Romanesque architecture during the 11th and 12th centuries".
[14] The red sandstone for the building came from the mountains of the Palatine Forest and is thought to have been shipped down the channelled Speyerbach, a stream running from the mountains into the Rhine at Speyer.
In designing the faxc3xa7ade of the westwork, Heinrich Hxc3xbcbsch, an architect of early Historicism, created a Neo Romanesque design which drew on features of the original westwork and those of several other Romanesque buildings, scaling the windows differently and introducing a gable on the facade, a row of statues over the main portal and polychrome stonework in sandstone yellow and rust.
The sandstone blocks alternate in colour between yellow and rust, a typical design of the Salian and Staufer era, and providing the context of the colour-scheme of the 19th century facade.
