Able to be seen from one place to another; when two locations can see each other directly without any obstacles.
The two towers are intervisible, allowing for clear communication between them.
Intervisible → It is formed from "inter-" (meaning between) and "visible" (from Latin "visibilis", meaning able to be seen). The word describes things that can be seen from one to the other, or are visible to each other across a distance.
Think of things that are 'between' ('inter-') each other and 'able to be seen' ('visible') — that's why intervisible means they can see each other.
