London Bridge spans the river Thames between the City of London and Southwark. Even though it was remodelled and reopened in 1973, there has actually been a bridge at this point of the river for almost 2,000 years. Over time, the bridge often stopped being used and was destroyed by a storm in 1091 and by fire in 1136. London Bridge was rebuilt in the 12th and 13th century, and 100 years later the southern gatehouse became the gruesome scene where the severed heads of traitors to the Kingdom were displayed impaled on pikes. The current bridge dates from 1973.
