Just like the Polio Fountain, the Domitian Temple had been dedicated to a Roman Emperor. Domitian was the first Emperor who allowed Ephesians erecting such monuments to the Romans and it was a great honor for the city of Ephesus.
The Temple had been constructed on the second floor of a terrace at Domitian Square and it consisted of thirteen columns at the long sides and eight columns at the short sides. There were another four columns in front of the cella. The ground floor of the building contained warehouses and shops.
Even though, initially, it was believed that the Emperor honored with that temple was Domitian yet, according to recent research in ancient Ephesus, it was erected for the emperor Titus.
