History

The bridge, which is still in use, was first described by the Englishman T.A.B. Spratt in his ''Travels and Researches in Crete'', after he had paid a visit to the site in 1853.

, while the Italian scholar Galliazzo dates the construction more precisely to the end of the 4th or beginning of the 3rd century BC. For the smaller, now collapsed southern bridge Nakassis cautiously supports a late Classical date.
