Marietta

Pennsylvania invented the American company town — coal patches and oil booms that burned bright and short.

Marietta is a borough in Lancaster County, Pennsylvania, United States. The population was 2,633 at the 2020 census. It is located on the east bank of the Susquehanna River, northwest of Columbia.

The on-the-ground condition of Marietta is unverified — it's listed here with unknown status. That could mean standing buildings, or an empty field. Go prepared for either, and consider sharing what you find so the record improves.

Nobody has confirmed the access situation, so treat any visit as reconnaissance: verify land ownership first, and be ready to admire from the road.

Here's the honest truth: access to Marietta is unverified. We couldn't confirm whether the site sits on public land, private property, or something in between — so verify land ownership and local rules before visiting, and respect private property at all times. The mapped point for Marietta is roughly 40.0572, -76.5558 — use it as a starting point and cross-reference a current topographic map before leaving pavement.

Ghost-town etiquette is simple: take only photographs. Removing artifacts is illegal on public lands and disrespectful everywhere else — and on federal land it can be a serious offense.
