For centuries, ecclesiastical architecture has produced some of the world's boldest, and best loved, buildings. Regardless of faith, churches become monuments of local pride, often dominating city skylines and standing as a universal symbol of the place they inhabit.

Church architecture has also been a place for innovation. We can thank the church for ushering in the perfection of domes.

Not all these buildings scream "church," however all are outstanding examples of what religion has gifted the built environment.
