Why it's on the list

A five-pointed star fort, the same geometry found on every continent.

Hidden history

Found, Not Built

A five-pointed star fort ringed by double moats, built in 1593 and restored between 1967 and 1992 to how it looked in the mid-1700s.

  1. Why researchers flag it

    A five-pointed star fort, the same geometry found on every continent.

  2. The star shape

    The same pointed-bastion star plan appears from the Netherlands to Japan to the Americas. Researchers ask why one geometry turns up on every continent.

  3. Restored to a date

    It was rebuilt to its mid-18th-century state. The question: what did restorers find under the later fill?

Questions worth asking

  • Why the same star geometry everywhere?
  • Were star forts only for cannon, or for something else?

Possible original uses

  • Fort
  • Village
