A small, fortified town that served as an outpost for the Ḥaḑramawt kingdom from the first to seventh centuries. The archaeological site and its surrounding landscape are known by the modern name Khor Rori, and the town is tentatively identified as Ptolemy's Abyssapolis, and the port of Moscha Limen of the Periplus Maris Erythraei.

This site is written up at It interests me because we have an Abisson in Britain, possibly near Portpatrick on the SW coast of Scotland next to the sea trench in the North Channel across to Ireland, where ancient mariners would have been aware that deep sea would prevent safety anchoring if caught off a lee shore. Much the same holds for Khor Rori on the coast of Oman. Therefore I question the assertion in Wikipedia that the name derived from waterfalls upstream from the ancient port. Also Ptolemy mentioned Αβυσσαπολις and I have not find an authority for Abyssa.
