The neighborhood kids might use a tree house as a lookout, from which they can keep an eye out for the local bully.

A lookout is usually so high that a person can see for a long distance in many directions when she stands on or in it. Armies sometimes use lookouts to scout for approaching troops, and navy ships include a lookout at the top of a tall mast, also called a "crow's nest." Lookout can also be spelled as a hyphenated word, "look-out," and used as well to refer to the person whose job it is to stay in the lookout and keep watch.
