Above one of the villages of Gorgopotamos lies the historic bridge of the same name, which joins the two slopes of Oiti and crosses the railway line of Athens to Thessaloniki.
On this bridge was written one of the most famous pages of modern history. On the night of November 25th, 1942, the united resistance forces of EAM and EDES along with British saboteurs, after a decision made by the Middle East Allied Headquarters, blew the bridge up causing a long delay in the transition of the Germans, putting pressure on the allies in Africa.
The bridge was rebuilt in 1948. It is 211 metres long and 30 metres high. On the small hill, a few metres away, there is a yearly gathering of representatives of the state and resistance organizations to honour the achievement of November 25th, 1942, which expresses, amongst other things, the unity of the Occupation fight against the forces of violence.
