The Krämerbrücke (Merchants' bridge) is a medieval bridge which is lined with inhabited, half timbered buildings on both sides. The bridge was built next to a ford and was part of the Via Regia, a medieval trade and pilgrims' road network, which linked Rome with the Baltic Sea, and Moscow with Santiago de Compostela in northern Spain.
Originally constructed from wood, the bridge was first mentioned in 1117 after its destruction by one of the many fires. The first documentary evidence dates back to 1156. Merchants and trades people had already set up market stalls on both sides of the bridge by this date.
Because of repeated fires in 1175, 1178, 1213, 1222, 1245, 1265, and 1293, the municipal administration acquired all bridge rights from the monasteries in 1293 in order to build a stone bridge. This was completed in 1325, with uninhabited, half-timbered trading stalls on top of it. At both bridgeheads stone churches dedicated St. Benedicti and St. Aegidien were erected.
After a fire in 1472, which destroyed nearly half of the city and the market stalls on the bridge, it was reconstructed in its current form with 62 half-timbered buildings. The three-storey houses are 13 m to 15 m in height. To make them habitable, the depth was extended by using wooden Sprengwerke (trusses or bracing) next to the arched vaults, so that the buildings partially overhang the stone bridge structure. The width of the bridge, as completed in 1486, is 26 m.
The name Krämerbrücke, which means 'merchants' bridge', has been in common usage since 1510.
The St. Benedicti Church was sold in 1807 and later demolished, apart from its tower, in 1810, in order to build a new house. In 1895 the tower had to give way to the newly built Rathausbrücke (town hall bridge), which crosses the river parallel to the Krämerbrücke. When the Rathausbrücke was being planned, the idea of completely demolishing the Krämerbrücke was discussed.
Because of its special significance in Erfurt's history, and the history of European medieval architecture in general, the Krämerbrücke was granted special preservation status. All buildings were restored from 1967 to 1973 and extensive repair works were done to the vaults in 1985/1986 and 2002. Today the shops at street level house businesses such as antique shops, wine merchants, art galleries, artisans' workshops and specialist food outlets, cafes, etc. A bakery operates from a shop under the bridge at its western end. The upper levels of the buildings are mainly inhabited apartments.
The bridge is one of Erfurt's main tourist attractions and a must-see, as the only other remaining medieval bridge of a similar type is the Ponte Vecchio in Florence. The Krämerbrücke is still in fairly much the same use as it has been for over 500 hundred years.References:
Roman Walls of Lugo are an exceptional architectural, archaeological and constructive legacy of Roman engineering, dating from the 3rd and 4th centuries AD. The Walls are built of internal and external stone facings of slate with some granite, with a core filling of a conglomerate of slate slabs and worked stone pieces from Roman buildings, interlocked with lime mortar.
Their total length of 2117 m in the shape of an oblong rectangle occupies an area of 1.68 ha. Their height varies between 8 and 10 m, with a width of 4.2 m, reaching 7 m in some specific points. The walls still contain 85 external towers, 10 gates (five of which are original and five that were opened in modern times), four staircases and two ramps providing access to the walkway along the top of the walls, one of which is internal and the other external. Each tower contained access stairs leading from the intervallum to the wall walk of town wall, of which a total of 21 have been discovered to date.
The defences of Lugo are the most complete and best preserved example of Roman military architecture in the Western Roman Empire.
Despite the renovation work carried out, the walls conserve their original layout and the construction features associated with their defensive purpose, with walls, battlements, towers, fortifications, both modern and original gates and stairways, and a moat.
Since they were built, the walls have defined the layout and growth of the city, which was declared a Historical-Artistic Ensemble in 1973, forming a part of it and becoming an emblematic structure that can be freely accessed to walk along. The local inhabitants and visitors alike have used them as an area for enjoyment and as a part of urban life for centuries.
The fortifications were added to UNESCO"s World Heritage List in late 2000 and are a popular tourist attraction.
