Christian prayer is an important activity in Christianity, and there are several different forms used for this practice.
A prie-dieu, which is used for private Christian prayer, situated in the room of a historic house.
Many devout Christians have a home altar at which they (and their family members) pray and read Christian devotional literature, sometimes while kneeling at a prie-dieu.

A bell tower is a tower that contains one or more bells, or that is designed to hold bells even if it has none. Such a tower commonly serves as part of a Christian church, and will contain church bells, but there are also many secular bell towers, often part of a municipal building, an educational establishment, or a tower built specifically to house a carillon. Church bell towers often incorporate clocks, and secular towers usually do, as a public service.
