Roman houses in Pompeii followed a basic floor plan that included an entranceway, atrium, courtyard, and private and service quarters. The atrium was a public area decorated to impress guests, while the peristyle courtyard contained gardens, statues, and fountains and allowed air and light to enter. Wealthy Romans decorated their homes with mosaics, frescoes, and artwork depicting Greek mythology, which were displayed in areas like the atrium and dining rooms.
