A property subject to an easement is known legally as a "servient estate," while a person or entity with a positive right granted by an easement is called a "dominant estate."
Easements can be established by explicit provisions in a written document like a deed, and can also arise over time from habitual use. If people cross a piece of private property to get to a beach, for example, and that behavior continues for several decades, this might create a public right of way.
It's a good idea to establish whether your estate has any easements attached before you start any construction projects, especially along property lines.
