Ташköпрю: Древний мост над рекой Сейхан в Адане.

Taşköprü (, ), historically known as Ponte Sarus, is a Roman bridge spanning the Seyhan River in Adana that was probably built in the first half of the second century AD. The bridge was a key link in ancient trade routes from the Mediterranean Sea to Anatolia and Persia. Until its closure in 2007, it was one of the oldest bridges in the world open to motorized vehicles. Since 2007 it has only carried foot traffic, and now hosts social and cultural events. Among the names used for the bridge during its history are the Saros Bridge, the Bridge of Justinian, the al Walid Bridge and Taşköprü ("Stone Bridge" in Turkish).

Although a variety of materials have been used throughout the many periods of construction and restoration, the bridge was generally built of tufa, marble and spolia. The eastern section of the bridge in particular bears many marks of the original construction. The bridge was constructed using the wall filling technique. The current length of the bridge is The Ottoman traveler Evliya Çelebi recorded a length of 550 feet (168 m) at the time of his visit. The bridge has 21 arches: 15 primary arches to carry the deck across the river and six small relieving arches within the larger piers. The bridge was shortened as portions of the approach at either end were buried during work to stabilize the river banks. The roadway is paved with cobblestones and is wide, including the sidewalks. The bridge's sculptural decoration includes a lion relief on the north side of the 11th arch, and various star and crescent artwork. Engravings published in the accounts of travelers to the Ottoman Empire depict the roadway as too narrow to accommodate two horse carriages side by side. It is thought that the deck was originally no more than across and was widened in the early 20th century. As a result of the widening work, new arches were added to the downstream side of the bridge. It is unclear when these additions are made, but there are records of an extensive restoration by the State Highway Agency in 1948. After the additions, the width of the roadway was extended to about or
The cobblestone pavement—the subject of many folk songs—was built by Adana Governor Süleyman Bahri Paşa (1899–1908). A pavilion supported on four columns was built midway across the bridge by the Governor Mahmut Paşa but was later demolished. The piers supporting the arches have become quite worn over time. They show several interesting architectural techniques. The bossage technique is visible on the downstream side of the eastern piers. The upstream faces of the piers show stepped cutwaters and footings. These stepped piers are a feature typical of Roman construction. Two of the relieving arches (the fifth and seventh arches from the western end) have their upstream side open but have been filled on the downstream side. The dimensions of the arches all differ due to the complex history of its construction. The upstream faces of the piers now have triangular cutwaters. These were all rebuilt during one of the Ottoman restorations, which accounts for their uniform appearance today.

In 2007 the bridge was closed to motorized vehicles. Since then, it has become a site for social and cultural events. Surveys in 1996 and 2008 identified the bridge as the location most commonly associated with Adana by its residents. The researchers conjecture that this is more due to its function as a landmark than to widespread knowledge of its history. They propose using the bridge as "a starting point for reclamation of the city's identity".
