Gerrha (Arabic al-Jar?a), was an ancient city of Arabia, on the west side of the Persian Gulf. More accurately, the ancient city of Gerrha has been located to exist at one time near or under the present fort of Uqair. This fort is 50 miles northeast of Al-Hasa in the eastern province of Saudi Arabia. Gerrha and Uqair are archaeological sites on the eastern coast of the Arabian peninsula only 60 miles from the ancient burial grounds of Dilmun on the island of Bahrain. (The Arabian Gulf in Antiquity, Vol. II. Potts, p. 56, Looking for Dilmun, Geoffrey Bibby, p. 7).

It was described by Strabo (Bk. xvi.) as inhabited by Chaldean exiles from Babylon, who built their houses of salt and repaired them by the application of salt water. Pliny (lust. Nat. vi. 32) says it was 5 miles in circumference with towers built of square blocks of salt.

Various identifications of the site have been attempted, JPB D?Anville choosing El Katif, Carsten Niebuhr preferring Kuwait and C Forster suggesting the ruins at the head of the bay behind the islands of Bahrain.
