Archaeological sites come in many shapes and sizes but whenever development is proposed they all have one thing in common. They are, in theory, capable of being protected in some way. Notwithstanding that some planning authorities may not wish to intervene or that landowners may refuse access, legislative powers exist for their protection. How they are used will depend on the location, nature and importance of the site and the objectives of those responsible for their protection. Different circumstances will bring different protective measures into play.
