Panj Cheshmeh Bridge

The Panj Cheshmeh Bridge of Bonab, also known locally as "Besh Gozli Korpi", is located in Bonab County, East Azerbaijan Province. This historic structure spans the Sufi Chay River, about 600 metres from the eastern edge of the city of Bonab. Its symmetrical, artistic design creates a striking sight that draws the attention of visitors. The bridge was added to Iran's National Heritage list on 25 Esfand 1379 (Solar Hijri) under registration number 3087. Panj Cheshmeh Bridge was built by Arbab Ali Akbar Yazdani, son of Samad Bonabi, to make it easier for caravans to cross the Sufi Chay River, since Bonab lay on the Silk Road and was of great economic and commercial importance.

The bridge dates back to the Safavid era and was probably restored in later periods. It is regarded as one of the region's outstanding architectural works. Its structure consists of five spans, or "cheshmeh", with pointed arches that, besides their architectural beauty, increase the bridge's resistance to flood currents. The materials used in the structure are a combination of stone, brick and sarooj mortar, which ensures the bridge's durability and stability. The bridge is estimated to be about 50 metres long and roughly 8.5 metres wide, and to rise about 5.8 metres from the riverbed to the top of the bridge. The deck is paved with stone, and on both sides there is a brick parapet one metre high that serves as a railing. Beyond their architectural and engineering significance, the bridge's five-arch piers also served a practical purpose: when the river ran high, they prevented the structure from being destroyed, which reflects the technical knowledge and skill of past engineers in designing stable, durable bridges. These features have made the Panj Cheshmeh Bridge of Bonab one of the most notable historic and tourist sites in East Azerbaijan Province.

To reach the Panj Cheshmeh Bridge of Bonab, drive from the city of Bonab toward the village of Sur, as the bridge lies along this local road. Given its riverside and historic setting, the best times to visit are spring and autumn, when the river's flow and the light offer the best conditions for photography and for admiring the bridge's architecture. Responsible nature tourism matters in this area: do not throw litter along the riverbank, do not damage the historic fabric of the bridge, and take care not to put pressure on the piers or arches during your visit.
