Termessos Ancient City is one of the most striking archaeological sites in Turkey, perched high on the Güllük Mountain (Solymos) in the Taurus Mountains, near Antalya province. Established by the Psidians, an indigenous Anatolian people, Termessos was a Pisidian city of antiquity and famously resisted Alexander the Great's siege in 333 BC. The site is renowned for its well-preserved ruins, which include an impressive theater that boasts a panoramic view of the surrounding mountains, the remains of various temples, an agora, a gymnasium, and an intricate system of cisterns that provided water to the city. The city's necropolis, filled with elaborate tombs, is also a significant feature. Due to its natural fortifications and elevation at over 1000 meters, Termessos is one of the few ancient cities to have never been conquered. The remoteness and altitude provide a natural shield, preserving its structures from extensive human touch and making it a fascinating snapshot of the past. Due to its location within the Termessos National Park, the area is also a haven for wildlife and native flora, blending cultural heritage with natural beauty.
