Only four bridges lined with buildings on both sides exist—and they are all in Europe: the Rialto Bridge in Venice, Italy; the Ponte Vecchio (Old Bridge) in Florence, Italy; the Pulteney Bridge in Bath, England; and the Krämerbrücke (the Merchant’s Bridge) in Erfurt, Germany.
The Krämerbrücke
Pilgrims today cross the Krämerbrücke (the Merchant’s Bridge) when walking one route of the Camino de Santiago. The bridge was once part of an important Medieval trade route, called the Via Regia, which connected Rome with the Baltic Sea, and Moscow with the Cathedral of Santiago de Compostela in northwestern Spain.A wooden bridge was first built on the site between the eighth and 11th centuries, and records show that market stalls have existed on the bridge since 1156. In 1325, the Krämerbrücke was rebuilt in limestone and sandstone as a medieval arch bridge. Between 1472 and 1486, 62 three-story half-timbered houses were built on the bridge. Over time, the houses merged to create 32 larger buildings, with shops occupying the ground floor level and living quarters in the upper levels.
