On the Greek island of Hydra you will find monasteries, churches, chapels and road side offeratories (I am still searching for the correct name for the little religious boxes that contain candles, matches etc so you can make your prayer offering,) with most of the larger open to the public when not formally being used for a service. The larger buildings such as the Cathedral of the Assumption of the Virgin Mary are designated as a monastery, which means that weddings cannot be conducted in them (only baptisms & funerals).
