The Roman Theater in Alexandria in Kom El Dekka is one of the ruins of the Roman era and it was built at the beginning of the fourth century AD.
It was discovered by chance, during the removal of dust to search for the tomb of Alexander the Great by the Polish expedition in 1960. Archaeologists called it the Roman Theater when the marble steps were discovered, but controversy arose over the function of this archaeological building. It took about 30 years to find it.
