If you visit somewhere in Sumatera, you often meet Megalith archaeological sites. My friends and I also visit one of them at Siallagan Village, Simanindo Sub district, Samosir Island, North Sumatera – Indonesia. We visited Parubalangan Stone chair salt; in Indonesia, we call it Parubalungan Kursi Batu Sira. This relic is the oldest King Sialagan archeological remains. Sira stone chair is a place as a court and penalization for criminals; thief, rapist, and killer.
