Yesemek Quarry and Sculpture Workshop is an open-air museum and archaeological site in Gaziantep Province, Turkey.

The site was a quarry in Hittite times and occupies a 100000 m2 area, making it the largest known stonemasonry workshop from the ancient Near East.

The ruins were partially unearthed by Austrian archaeologist Felix von Luschan during his excavations at Zincirli to the north of the area in 1890.

[4] The most recent work was carried out in the 1990s by İlhan Temizsoy, director of the Museum of Anatolian Civilizations and brought another hundred objects to light.

These sphinxes and lions were probably intended to flank the gates of Hittite cities, palaces and temples, and are very similar to the door sculptures found at Hattusa and Alaca Höyük.

In addition, there are groups of mountain gods with arms crossed over their chests, reliefs of hunting scenes, and a bear-person.

In the quarry, large blocks of red basalt were broken up, by striking pre-existing cracks with hammer and chisel.
