Yes... "Qustaniniyah" is "Constantinople" the old capital of Ottoman Empire . Algiers "the capital of Algeria" has this name for a long time ago ..In arabic "ALJAZAIR" which means in english "The islands" ..taken this name because there were small islands in front of this city .there few old coins struck in algeries ..most of them are struck in other cities of algeria because algeries was not a capital of an islamic empire .
