High structure is a term used to describe a building or structure that is tall and imposing. The two most common examples of high structures are steeples and towers. A STEEPLE is a tall, pointed structure typically found on top of a church or other religious building. It is usually made of stone or wood and is often decorated with ornate carvings. A TOWER is a tall, vertical structure that can be used for a variety of purposes, such as observation, communication, or defense. Towers can be made of stone, brick, metal, or wood and can range in height from a few feet to hundreds of feet.
