Ceuta is an autonomous city of Spain on the north coast of Africa. Bordered by Morocco, it lies along the boundary between the Mediterranean Sea and the Atlantic Ocean. The coastline is popular for scuba diving, as this is the place where the waters of the Atlantic Ocean and the Mediterranean Sea meet and mingle together, thus encouraging a constant regeneration of its flora and fauna.
