Cap. 16 Art. 323Ownership of land carries with it ownership of what is above and under it.

Whosoever has the ownership of the land, has also that of the space above it, and of everything on or over or under the surface; he may make upon his land any construction or plantation, and, under it, any work or excavation, and draw therefrom any products which they may yield, saving, however, the provisions relating to Praedial Easements under Title IV of Part I of Book Second of this Code and any other provision of law in regard to fortifications or other works of defence.
