Architecture includes houses, religious buildings like temples and tombs, and public building like city walls, theaters, stadia, and stoas.
Sculpture includes small figurines and life-size statues, but also relief sculptures which were on the sides of buildings, and also tombstones.
We have very little Greek painting from the Classical period; most of what we have is from the Bronze Age. The paintings were painted on walls, as decoration for rooms, like murals or wallpaper. On the other hand, we have a good deal of painted pottery from all periods of Greek history (down to the Hellenistic).
