A hypostyle hall is a hall with a roof supported by rows of columns. It is typically enclosed on all sides and provides a large, covered space for public gatherings, ceremonies, and religious rituals. Examples of hypostyle halls in ancient architecture include the Hall of Columns in Karnak, Egypt, and the Great Mosque of Cordoba, Spain.
A peristyle, on the other hand, is a colonnaded courtyard or porch surrounding a building or a central space. It is typically open to the sky and provides a sheltered outdoor space for social gatherings, receptions, and public events. Examples of peristyles in ancient architecture include the Peristyle at the Roman Villa of Mysteries in Pompeii, Italy, and the Peristyle of the Parthenon in Athens, Greece.
