Bridge tower

A bridge tower (Brückenturm) was a type of fortified tower built on a bridge. They were typically built in the period up to early modern times as part of a city or town wall or castle. There is usually a tower and both ends of the bridge. Tower Bridge in London is perhaps the best known example but there are many in Europe.

Function
These towers were built in pre-medieval and medieval times to guard access to the bridge and to enable the charging of tolls on important roads crossing rivers, usually near towns and cities. The rivers were often part of the defences of these settlements. As a result it was important from a defensive perspective that the bridges did not allow attacking enemies to break in. The bridges acted as a bulwark and often had a small drawbridge. In addition to their genuine protective and defensive functions they also played a symbolic and architectural role. Often these towers were the first public buildings that the travellers saw when approaching the city.

The high cost of such towers was usually paid for by charging tolls. The gates of bridge towers were closed at night, so that no-one could cross the bridge during silent hours.
