What it is Filled

A building at or over the entrance to a castle, town, monastery, estate, factory or other enclosed site, controlling and guarding access and often housing a porter, guards or officials; medieval gatehouses were fortified with gates, portcullis and towers, while later gatehouses are lodges and security posts.

Why it exists Filled

Let an agent identify a gatehouse and its kind, explain its function and architecture, relay heritage status and visiting information, and separate gatehouses from gates, lodges and barbicans.

Distinguishing features Filled

  • Controls an entrance

Only with a human decision

  • Refusing or granting entry in a disputed or emergency case.

May

  • Describe the history and architecture of gatehouses.
  • Manage visitor logs and access at a gatehouse for the site operator that authorized it.

Moral aspects Filled

  • Gatehouses decide who enters; that power can exclude people unfairly.
  • Historic gatehouses are heritage that belongs to future generations.

Who is affected

  • Visitors and workers
  • Residents of the site
  • Heritage owners
