Vedius Gymnasium is easily seen when entering the Ephesus city from the south entrance. The construction of the gymnasium dates around the second century AD, funded by Publius Vedius Antoninus and his wife Flavia Papiana. They dedicated the gymnasium to Goddess Artemis and to Emperor Antoninus Pius. In Ephesus, gymnasiums were the schools for young people in which one could take lessons for art, sports, literature, drama and speech. The most important and beautiful of these gymnasiums was the Gymnasium of Vedius. The entrance of the gymnasium is on the east, and when entering there is a palaestra (courtyard), surrounded by columns. The hall of emperors is also on the east, with statues and floors covered with mosaics.
The gymnasium included a bath, with a tepidarium, a caldarium, and a frigidarium. There was a pool at the frigidarium, with the statue of the god of the River Kaistros in the north end, pouring water into the pool from the amphora that the god was leaning on. Today, the statute is displayed in Izmir Museum.
