Hertford Bridge, popularly known as the Bridge of Sighs, is a skyway joining two parts of Hertford College over New College Lane in Oxford, England.
Its distinctive design makes it a city landmark.
The bridge is often referred to as the Bridge of Sighs because of its supposed similarity to the famous Bridge of Sighs in Venice.
However, Hertford Bridge was never intended to be a replica of the Venetian bridge, and indeed it bears a closer resemblance to the Rialto Bridge in the same city.
There is a false legend saying that many decades ago, a survey of the health of students was taken, and as Hertford College's students were the heaviest, the college closed off the bridge to force them to take the stairs, giving them extra exercise.
However, if the bridge is not used, the students actually climb fewer stairs than if they do use the bridge.
