Stins
A stins is a former stronghold or villa in the province of Friesland, the Netherlands. Many stinsen carry the name "state".
Stinsen used to belong to noblemen or prominent citizens. Most stinsen were demolished in the 19th century, when maintenance became too expensive. Several surviving stinsen are now used as museums.
Stinsen also appear in East Frisia, and are known as borg in the province of Groningen.
