What it is Filled

A royal road of the Portuguese Crown; above all the network of colonial roads in Brazil, built from the late 17th century, that the Crown made the only legal routes between the gold and diamond districts of Minas Gerais and the ports of Paraty and Rio de Janeiro.

Why it exists Filled

Let an agent tell the historical Brazilian royal-road network apart from the modern tourist route that carries its name and from generic roads, and answer questions about its branches, history and protection.

Distinguishing features Filled

  • Established, maintained or controlled by the Crown, often on earlier routes and Indigenous paths, unlike private trails.
  • Tied to mining taxation and registry posts.
  • A historical network; the modern tourist route follows it only in part.
  • The words mean royal road; Portugal also had royal roads under that name, and in Spanish America the counterpart is camino real.

What robots and AI may and may not do Filled

Must not

  • present the tourist route as the exact historical alignment without saying so
  • give unsafe route advice for remote sections without noting conditions
  • assign ownership of heritage segments to a company

Only with a human decision

  • decisions on works affecting a protected segment

May

  • explain the history and branches of the network
  • describe the modern marked route for planning a trip

Moral aspects Filled

  • the roads followed Indigenous paths and were built and kept largely by enslaved Africans and Indigenous people
  • heritage protection versus local development

Who is affected

  • descendant communities along the route
  • residents of historic towns

Owners Filled

Steward

per segment: the road authority that maintains it and the heritage authority that protects it, recorded separately

Master systems

  • national heritage registers of Brazil

Links to other meta-models Filled

parent

  • Q83620 - registry parent class

related

  • road - a road of a specific legal status
  • camino real - the Spanish colonial counterpart
  • gold rush in Minas Gerais - the economic context that created it
  • historic town - colonial towns grew along it
  • estrada real in Portugal - royal roads of the Crown in Portugal

What else AI and robots need to interact with it Filled

Identity and identifiers required Filled

  • Vercy registry: vr.tr.estrada-real
  • Wikidata: Q866472 (https://www.wikidata.org/wiki/Q866472)

Direct properties not applicable Not applicable

Not applicable

A historical road network: length and condition differ by branch and segment and are recorded there.

Recognition required Filled

  • Original stone paving on steep sections near Paraty
  • Route marker posts of the modern tourist route
  • Colonial towns such as Ouro Preto, Tiradentes and Diamantina on the line
  • Stretches of dirt track and stone paving laid by enslaved workers, with bridges, registry posts and colonial towns along the way; today partly overlaid by modern roads and marked with route signs.

Capabilities and actions required Filled

  • identify which branch a town or segment belongs to
  • explain the role of the roads in the colonial gold cycle
  • plan a visit along the marked modern route
  • find heritage protection status of a segment

Hazards and failure modes required Filled

  • Erosion and loss of original paving
  • Confusing the tourism brand with the historical alignment
  • Remote sections with poor signage for walkers and cyclists

Standards and interfaces required Filled

  • Heritage protection of segments and towns by IPHAN, the national heritage institute of Brazil
  • Historic Town of Ouro Preto and Diamantina on the UNESCO World Heritage List

Context of use required Filled

  • Moving gold, diamonds, goods and people under Crown control, so that taxes on mining could be collected at registry posts.
  • Caminho Velho (Paraty to Vila Rica)
  • Caminho Novo (Rio de Janeiro to Vila Rica)
  • Caminho dos Diamantes (Vila Rica to Diamantina)
  • Caminho do Sabarabucu
