Büyük Yazılıkaya is a historic site located in the Han district of Afyonkarahisar. Built by the Phrygians in the 7th century BC, this monument is one of the most significant structures in the Phrygian Valley and is also commonly known as the Midas Monument. The 17-meter-high rock-cut facade, adorned with geometric patterns and Old Phrygian inscriptions, served as an open-air shrine dedicated to the Phrygian mother goddess Matar Kubileya. It is within walking distance of the Midas Monument (45 m) and Küçük Yazılıkaya (237 m).
