Wat Tham Phra Phutthasaiyat, also known by the local name "Wat Tham Phra Thong" (Temple of the Golden Cave), is situated on a hill called "Phu Pha Thong" in Warichaphum District, Sakon Nakhon Province. The temple is a significant natural and artistic heritage site, built by adapting a natural rock shelter into a place of worship.

Inside the cave, a large Reclining Buddha image is enshrined. Several historical artifacts have also been discovered here, including a remaining high-relief Buddha carving on a cave wall and a stone inscription in ancient Khmer script. Scholars have translated the inscription, which reveals that the site was once a gathering place for 31 groups of monks led by a great monk named "Sriviriyabandit."

The temple was also once a repository for valuable artifacts, including gold, silver, and bronze Buddha images, which were later moved for safekeeping, giving the temple its alternate name, "Wat Tham Phra Thong."
