Culture / The crown of mosque

in Java culture, mosque is a sacred building where people can have a contact with the God. For that reason it must be built in special design. Thus they put an elaborate "crown" on top of it based on local Javanese concept. However, I found this mosque has a "different" crown. Local people simply put a "dome" style with "Allah" word on top (Arabian style), while the mosque main roof is in layers' style as typical Javanese Islam style.
