Many Egyptian gods and goddesses started in one place, and all through their history had their own city where they were worshipped, and many big cities and towns are known as the hometowns of their god or goddess. However, no local cities where Isis was worshipped have been found; all through her early history there are no known temples to her. Worship of Isis did not start until as late as the 30th dynasty; until that time Isis was worshiped in temples of other gods or goddesses. However, even in the 30th dynasty Isis was worshiped together with Horus and Osiris. Temples to Isis became common in the Roman times. There was a temple built to her at Philae.
