In 1030, Emperor Conrad II, founder of the Salian dynasty, laid the cornerstone of Speyer's Imperial Cathedral, the largest Romanesque church in the world
Speyer — Seal of the Salians
You are an imperial chronicler in the service of the Salian dynasty, tasked with a covert investigation in Speyer, circa 1030.
Your mission begins at Domplatz, before Conrad
Follow the footsteps of Conrad II through Speyer, the founding emperor of the Salian dynasty who erected Europe's largest Romanesque cathedral in 1030.
« Imperium Salicum aeternum »— Motto of the House of Salian, Official motto of the Salian dynasty (11th century)
The story that haunts this land
Speyer emerges from 1030 as the symbol of Conrad II's power, first emperor of the Salian dynasty. The cathedral he orders measures 134 meters long and 33 meters high under vault — dimensions making it the largest Romanesque basilica in Europe at that time. Its imperial crypt houses the remains of eight emperors and kings of the Holy Roman Empire, including Conrad II himself, who died in 1039. The 2.5-meter thick walls testify to its defensive function during the religious wars that would ravage the region.
Conrad II's statue, erected in 1860 by Johann von Halbig on Domplatz, honors the founder of this imperial lineage that ruled Central Europe for a century. The Gothic inscription carved on the base proclaims 'Dem Gründer des Domes und Stifter der Salischen Herrschaft' — to the cathedral's founder and initiator of Salian domination. This 150 by 100-meter square, developed in the 19th century, maintains its weekly market since the Middle Ages, perpetuating the imperial commercial tradition.
Maximilianstraße guides you 600 meters along the artery traced in the 13th century, bordered by merchant houses from the 16th-18th centuries. This street preserves its medieval alignment and leads to the Town Hall built in 1558-1761 in Rhenish Renaissance style. The Altpörtel, sole surviving gate of the fortifications, rises 55 meters since 1370-1390. This three-story tower, with its loopholes and 6-meter passage, served as prison before its museum restoration after the 1689 destructions.
The episcopal residence, built between 1697 and 1710 by Lothar Franz von Schönborn, illustrates Speyer's baroque renaissance after the War of Spanish Succession. This 4500 m² palace with 50 main rooms, partially destroyed in 1945 then restored until 1968, now houses the Historical Museum of the Palatinate. Its French gardens, reconstructed according to 18th-century plans, extend the princely aesthetic in the former imperial city.
The Domnapf, monumental fountain reconstructed in 1904, closes your journey at Domplatz's center. Its 12-meter basin in red Vosges sandstone, adorned with sculptures of the Palatinate's four rivers, draws water from an underground spring discovered in 1895. You leave Speyer with intimate understanding of an imperial power that shaped medieval Europe, engraved in every stone of this Rhenish city listed as UNESCO World Heritage since 1981.
