The Rotunda of Galerius is 125m northeast of the Arch of Galerius. It is now the Greek Orthodox Church of Agios Georgios, better known as the Church of the Rotunda (or simply The Rotunda). The cylindrical structure was built in 306 on the orders of the tetrarch Galerius, who was thought to have intended it to be his mausoleum. It was more likely intended as a temple; it is not known to what god it would have been dedicated.
