The medieval city

A city connected by trade

Medieval Erfurt stood where important long-distance routes met. The University of Erfurt’s account of the city identifies the Via Regia and the Nuremberg trade route as significant connections. Their importance lay in the movement of goods and people: the city belonged to networks reaching beyond its immediate countryside. 1

That wider setting helps make sense of the buildings encountered in the old town. A bridge could serve as a marketplace; commercial income could support civic ambition; scholars could be drawn to an urban centre with institutions of learning. The following places offer ways into those connections without assuming that every resident shared equally in the city’s wealth.

Woad: the work behind the blue

Waid, known in English as woad, was a plant used to produce blue dye. Demand for blue cloth made the dye a valuable export. The City Museum describes Erfurt as the leading German centre of the medieval woad trade and emphasises both the profits and the labour involved in processing it. 2

The finished colour conceals a demanding production history. Fermentation formed part of the process, which could create strong odours. The museum’s account places physical work and the less attractive conditions of manufacture alongside commercial success. Woad therefore connects the city’s prosperity with material production, rather than only with the impressive buildings wealth could pay for. 2

It is a useful reminder when reading a historic streetscape: a handsome façade can be the visible result of activities carried out elsewhere, by people whose names are less readily preserved.

Krämerbrücke: crossing, market and home

The Krämerbrücke, or Merchants’ Bridge, combines movement across the river with space for selling goods. Its historical chronology records a wooden predecessor and identifies a written reference in 1156 that describes the bridge as a place of goods offered for sale. The stone bridge was completed in 1325. 3

Control over this trading space mattered. The emerging city council acquired rights held by religious institutions as it sought authority over the bridge and its commerce. Imported goods sold there included spices and silk: the crossing belonged to a commercial world extending well beyond Erfurt. 3

The bridge’s houses also have a history of alteration. After the major city fire of 1472, the bridge was widened and rebuilt with permanent houses. Today’s appearance should therefore be read as the outcome of successive changes, rather than as a complete scene preserved untouched from 1325. 3

Jewish life within the city

The Alte Synagoge, or Old Synagogue, the Mikveh, a Jewish ritual bath, and the Stone House preserve evidence of religious and domestic life. Together they form the Jewish-Medieval Heritage of Erfurt inscribed on UNESCO’s World Heritage List in 2023. The recognised ensemble includes both communal and secular architecture. 4

Their location is part of their significance. These buildings were integrated into the town’s physical fabric and adapted to its local construction traditions. They allow Jewish history to be understood within the history of Erfurt’s streets and neighbourhoods. 4

The municipal history describes Jewish and Christian neighbours living close together in the central area around the synagogue. Documents record financial and commercial relationships, while surviving Hebrew manuscripts testify to scholarship. Everyday proximity, business and intellectual life were all part of the community’s experience. 5

1349 and the limits of protection

On 21 March 1349, a pogrom destroyed Erfurt’s Jewish community. False accusations of well-poisoning were used to justify violence during the wider wave of persecution associated with the plague. The city’s account also identifies religious hatred, indebtedness and political interests among the factors behind the attack. 5

Jewish residents returned, probably from 1354, and a second community developed. Its members included wealthy families and poorer people working in varied trades. In 1453 the council revoked protection; from 1454 Jewish residence was no longer tolerated. These decisions make clear why the city’s prosperity cannot be treated as evidence of equal security or belonging. 5

The architectural remains should be read alongside this history of violence and exclusion, while also preserving the fuller account of the lives once lived within them.

A university shaped by civic ambition

Erfurt received a papal university privilege in 1379, followed by a renewed privilege in 1389. Teaching began in 1392. Distinguishing these dates avoids treating official authorisation and the opening of an institution as the same event. 6

The university’s founding was driven by civic initiative. Its four faculties covered philosophy, medicine, law and theology. Buildings around the Collegium maius, the main university building, recall the academic quarter and a city whose connections included learning as well as trade. Martin Luther would later study here. 6

Read together, the bridge, Jewish heritage and university present a city of exchange, institutions and unequal power. Return to the Reformation chapter to follow the next stage, or revisit Erfurt’s early beginnings to see how different kinds of evidence anchor the longer story.
