Covered Hippodrome seems to have been either a garden in shape of the hippodrome (as at the Domus Augustana and Domitian´s Albanum Palace in Rome and Hadrian´s villa at Tivoli) or a long corridor, with curved ends and the interior longitudinally divided by a middle wall, used for horse rides or even for private chariot races (such as the so-called Poikile structure in Hadrian´s villa or the long corridor in the Sesorian palace in Rome).
