Roman houses for wealthy families, or domus, were centered around an open-air courtyard called an atrium. The main rooms included the tablinum, which was the father's study, and cubiculum, or bedrooms. Other rooms were the triclinium for dining, culina for cooking, and peristylium, another courtyard. Poorer Romans lived in insulae apartment buildings with shops on the ground level and small flats above. Temples housed statues of the gods and were considered their homes.
