The Temple of Apollo in Side, Turkey, also known as the Side Temple or the Apollon Temple, is an ancient Greek temple that dates back to the 2nd century AD. Side was a major port city in ancient times, and the temple was a central place of worship for the people of the city.

The temple was built in the Ionic style and originally had eleven columns on the long sides and six on the short sides. Today, only a few of the columns remain standing, but the ruins of the temple are still an impressive sight.

The temple was dedicated to Apollo, the Greek god of music, poetry, prophecy, and healing. The cult of Apollo was very important in ancient Greece, and many temples were built in his honor throughout the country. The Temple of Apollo in Side was one of the largest and most impressive of these temples.

In addition to the temple itself, there were also other buildings and structures associated with the temple complex, including a library and a large square or plaza. The plaza was likely used for public gatherings and festivals, and it is thought that the temple complex was a major center of social and religious life in ancient Side.
