Orbital arch
From Halopedia, the Halo wiki
Orbital arches were a type of orbital construction used by the Precursors on Charum Hakkor. Like all Precursor technology, they were virtually indestructible.[1] On Charum Hakkor, prehistoric humans built cities onto the orbital arches, described by Bornstellar Makes Eternal Lasting as resembling "ivy growing on great trees".[2]
