Illuminate the exterior and entrances. Use motion-activated lighting near doors and windows. Keep shrubbery and trees trimmed so building can be observed by passing patrols. If in a rural setting, ensure crops are far enough away to allow proper illumination of the area. Do not allow church signs to block the view of the building.
Many churches have basement entries that are hidden from view.
These should be secured with locking ground-level doors when church is not in use. Ladders, external stairways and fire escapes allowing access to roof should be secured. Painting the building white or constructing it with light-colored brick makes a human figure more readily seen at night. Consider fencing the areas or sides that are not readily visible to patrols or neighbors. Windows that can be opened should have adequate locks on them.
