Ancient PlankRoads

A field atlas for translating named historical corridors into modern locations, surviving material evidence, and routes that can actually be investigated on the ground.

Research question / 01

How does a historic road become a place you can find?

Ancient route names rarely behave like a modern road number. A single name may describe a corridor, several alignments, or a network whose preferred path changed with repairs, warfare, settlement, and the landscape itself.

The atlas therefore treats every line as a hypothesis. It connects written sources to present-day administrative geography, then asks what material evidence still survives and how confidently each location can be reached.

Location model / 02

From historical name to exact site

Every record follows the same modern address chain. Coordinates supplement the chain; they never replace the names needed to ask directions locally.

  1. 01Province
  2. 02City
  3. 03County
  4. 04Township
  5. 05Village
  6. 06Site

Province → prefecture-level city → county → township → village → surviving site

Working corpus / 03

Nine route systems

These names are research units, not finalized GPS traces. Each remains open to alternate alignments and new field evidence.

Evidence index / 04

Six things to look for

01

Plank sockets

Carved holes, spacing, cliff face, tool marks, and their relationship to the reconstructed road line.

02

Road surfaces

Cut steps, wheel ruts, paving, retaining walls, and changes in width or construction material.

03

Inscriptions

Cliff texts, dated repairs, route names, donors, officials, and later reuse of an older passage.

04

Passes

Topographic control points, gates, defensive works, sightlines, and connections between valleys.

05

Stations

Postal stations, inns, settlements, water sources, and the practical spacing of a day’s journey.

06

Bridges

Bridge sites, surviving masonry, abutments, river crossings, ferries, and evidence of route change.

Evidence grade

A Observed and located

B Source-supported, field check pending

C Working hypothesis

Field protocol / 05

Before, on site, after

01Before departure

Build the evidence packet

Align historic names, gazetteer references, previous surveys, candidate coordinates, access notes, and unresolved questions before entering the field.

02At the site

Record position and uncertainty

Capture coordinates, approach direction, scale, material, four orientation views, ambient audio, and a spoken note that separates observation from interpretation.

03After return

Reconcile the route record

Archive original media, compare names and coordinates, grade the evidence, update the route hypothesis, and preserve contradictions instead of smoothing them away.

Working principle / 06

The route is not a line.It is a chain of evidence.

The project remains deliberately open: every visit can confirm a site, weaken an inherited assumption, or reveal that the road took another path.
