in the trailer they showed this cathedral as a english wonder
i think this is Canterbury Cathedral in england
i suggest to add notre dame cathedral as frankish wonder
and add hagia sophia cathedral as byzantine wonder ( the turks they transformed it to mosque)
and blue mosque as turkish wonder
al azhar mosque as arabs ( saracens ) wonder
al azhar mosque is located in egypt and it was build in 972, its most important mosque in egypt and in all islamic world
