Gotlar Sütunu

A Roman monumental column standing among trees on the Sarayburnu side of Gülhane Park, beside the outer gardens of Topkapı Palace. The shaft, about 18.5 metres high, is a single piece of Proconnesian marble with a Corinthian capital. The Latin inscription on its base commemorates a victory over the Goths; the column is dated to the 3rd or 4th century and linked with Claudius II Gothicus or Constantine I. According to Wikipedia it is the oldest surviving Roman monument in the city. A statue once stood on top.
