This covered Ottoman-era bazaar features a nearly bewildering array of copper works from the copper workshops at the nearby castle, as well as a large number of hand-woven and machine-made carpets. The ambiance and the architecture make it well worth the visit even if copper and interior décor are not on your must-have list.

Imposing and solid, Gaziantep Castle has been undergoing extensive beautification and restoration efforts which have yielded interesting archaeological finds that have, unfortunately, done little to illuminate its obscure origins. The bulk of the structure in its current form dates back to the reign of the Byzantine Emperor Justinian in the 6th century C.E. Despite this, it is certain that several of the remaining towers are of Roman origin. Based on inscriptions, other towers must date from the Ottoman-era, and there is also evidence of a ruined mosque.

Photographs of brave martyrs who valiantly resisted French invaders during the Turkish War of Independence are set side-by-side with antique weapons, each bearing silent witness to the sacrifice these men and women made for the Republic. Set around a courtyard covered in multi-coloured stone, there are many artefacts from the region on display, as well as lifelike models of people engaging in daily life in Gaziantep as it looked during bygone eras. 

This museum boasts an extensive array of artefacts from the Neolithic Age to the Byzantine Empire. Neolithic ceramic pieces, figures, and seals from the Bronze Age, stone and bronze objects, jewellery, ceramics, coins, glass objects, mosaics and statues from the Hittite, Erratum, Persian, Roman and Byzantine periods have been collected under the same roof in well-presented, informative exhibits.

This 2,248 square mt (24,297 square foot) museum contains an unrivalled collection of antique mosaics from the Roman and Late Antique periods. Turkish bath mosaics, mosaics found in villas located on the banks of the Euphrates, such as mosaics from the Poseidon and Euphrates villas, as well as those from the Dionysus villas, are on display here. A section containing Byzantine church mosaics is particularly noteworthy.

Rumkale was a key Byzantine fortress on the river Euphrates. The fortress, now situated across a peninsula created by the reservoir of Birecik Dam is currently only accessible by boat; however, it will soon re-open for visitors following an extensive restoration project that includes a new footbridge and several cafes.
