number of towers
The quantity of distinct towers rising over the main roofline of a structure.
Common types of towers counted in this field are steeples, minarets, bell towers, and fortification towers.
Spires, finials, fleches, lanterns, turrets, and other small or medium-sized decorative towers which start at the roof, setback, or cornice level, should not be counted as towers.
Freestanding towers (such as bell towers or minarets), which are not attached to the building being described, should not be counted as towers for that building.
This field may apply to many types of building, but is especially common in religious structures (e.g. churches and mosques) as well as castles.
