Shorapani is an ancient town founded in the 3rd century B.C. It was first mentioned in written sources in the 1st century B.C. by a famous Greek historian and geographer Strabo. Shorapani is also mentioned in Greek mythology as a place where Jason and the Argonauts arrived during their trip around Colchis. According to Vakhushti Bagrationi, a Georgian Royal Prince, famous geographer, historian and cartographer from the 18th century, the town used to be the centre of Argveta Principality.
There is a fortress in the town which was built by King Parnavaz I of Kartli in the 3rd century BC. It was located in a strategic place, therefore over the centuries it was attacked many times. The fortress is connected with the Kvirila River through a 60-meter-long tunnel from the 6th century. Nowadays, only the ruins of the fortress remained, and the items found during excavations in Shorapani are kept in Zestafoni Museum.
