The bridge is estimated to be over 2,500 years old, dating back to the Kingdom of Lydia.
The structure utilizes a unique 'keystone' engineering technique that has allowed it to survive numerous seismic events in the region.
It is built directly over the Banaz Çayı (Banaz Stream), which serves as a vital irrigation source for the local agriculture.
The stones used for construction were sourced from local quarries in the Uşak plateau.
The bridge was designed to withstand significant seasonal floodwaters characteristic of the river canyon.
Cilandiras Bridge is a single-arch stone bridge spanning the Banaz Stream in the Karahallı district of Uşak province. Constructed during the Hellenistic period, the structure features a span of 24 meters and a height of 17 meters from the water level. The bridge is composed of cut limestone blocks assembled without mortar. It was historically positioned on a critical caravan route connecting the Phrygian and Lydian regions. Recent restoration efforts have reinforced the original masonry to preserve the integrity of the arch. The surrounding topography includes high, rocky canyon walls that characterize the local geography.
The viewing platform located on the canyon ridge directly above the bridge for a full overhead composition.
Wear sturdy hiking shoes with good grip as the terrain leading down to the riverbank is uneven.
Visit during the spring months to see the stream at its highest flow, which provides the most dramatic visual contrast with the stone arch.
Bring sun protection, as the canyon area offers minimal shade once you leave the immediate bridge vicinity.
Do not attempt to climb or walk across the top of the arch for safety reasons and to protect the ancient stonework.
