In Egyptian temples, the roofless space surrounded by columns that preceded the hypostyle room is called the hypostyle room.

Hypeter[8]​ was the temple without a roof, like the so-called kiosk of Trajan")[9]​ in Philé. It is a Latin term (hypaethrus) derived from the Greek ὕπαιθρος (hupaithros, built with the prefix ὑπό -hupo, "below"- and the root αἰθήρ -aither, "the sky" or "the air"-), which also applies to non-Egyptian temples, such as the Temple of Apollo at Didyma. Its opposite term is cleithron (κλεῖθρον), which designates the completely covered temple.[10] Vitruvius uses hypaethrus to designate the zenithal opening of the roof of the decastyle temples"); although no examples have been found in Rome, and a Greek example is octostylo") (the temple of Olympian Jupiter in Athens "Temple of Olympian Zeus (Athens)")).[11]​.

Liwan "Liwan (architecture)") is the name of a dependency of a certain type of traditional housing of the Mediterranean Levant, which is compared to Greco-Roman peristyles.[12]​.

The prayer hall of mosques (haram or musalla) is also called liwan, which is usually characterized by the plurality of arches, which give a true "forest of columns", but it is usually a covered space, accessed from the ablution courtyard (sahn), which does respond to the concept of peristyle: a courtyard surrounded by porticos.

These concepts should not be confused with that of iwan, a pavilion closed on three sides, also in the context of mosques (in this case, those of Central Asia).

In Islamic architecture, especially in palaces"), porticoed patios are developed, very often around fountains and water features (sadirvan"))[13]​ like those of the Alhambra.
