On the slope of a hill overlooking the ancient city of Ephesus, six terrace houses constructed in the 1st and 2nd centuries C.E. provide an introduction into the daily life of the city's wealthier citizens. The houses measure between 90 and 550 square meters, and the mosaic courtyards, advanced heating systems and hot and cold running water show how the ancient city of Ephesus was an advanced society. Two of the terrace houses are open to visitors, with a separate admission. Note that visiting the terrace houses requires ascending and descending many staircases and platforms erected alongside the ruins.
