Sequent Occupance

A landscape is never built once. It is built, lived in, half-changed, and built again, by whoever controls that place next. Sequent occupance names this layering: each successive culture or civilization leaves its own fingerprints on the land, buildings, street patterns, and place names, and those fingerprints tend to stick around even after that group loses control. The next occupant usually builds on top of or alongside what is already there rather than starting from bare ground, because reusing existing structures, roads, and farmland is easier than replacing them.

That is why old cities read like sediment. A cathedral becomes a mosque. A Roman road becomes a medieval trade route becomes a modern highway. A colonial grid of streets gets Spanish names, then independence-era renamings, with the old street signs sometimes still visible underneath. Each layer tells you who held power there and what they valued, and because removal is costly, most layers survive in some form, even if just as a foundation, a street name, or a building's bones.

Sequent occupance connects to the bigger idea that culture is written onto landscapes, which is why geographers can read a place's history just by walking through it, the same way they read religious hearths or language boundaries elsewhere in this unit. It also sets up a useful contrast: the normal pattern is partial survival, layer on layer, but sometimes a new power chooses total erasure instead, demolishing what came before rather than building beside it. That contrast, addition versus erasure, is what later questions in this topic test most directly.
