Tinnumburg

Tinnumburg is a ring fort on the North Sea island of Sylt with an earthen wall that rises about 8 meters high and spans roughly 120 meters across. The wall encloses a flat interior area and can be walked around on established paths.

The fortification was built around the first century AD and served the local population as a refuge against outside threats in the centuries that followed. The site was later abandoned and faded from memory until archaeologists investigated it multiple times.

The site is named after the Tinner, a North Frisian people, and today sits surrounded by pasture and grassland that visitors can walk through. The circular layout allows you to experience the former settlement on foot and understand how the space was organized.

The site is accessible year-round and can be explored at your own pace, with well-worn paths around the wall easy to follow. Good footwear is recommended since the ground can be uneven and the North Sea island can have unpredictable weather.

A small tidal creek flows northwest of the fort and once provided water access to the sea for inhabitants. This natural feature made the location strategically valuable and gave residents easier connection to fishing grounds and trade routes.
