Admission: Free to visit the ruins; museum tickets may apply for interior displays

Bohus Fortress is a medieval stone fortress overlooking the Göta River near Kungälv in Västra Götaland County, Sweden, founded in the early 14th century as a fortified seat on the Norwegian-Swedish frontier.

The site consists of extensive stone ruins of towers, curtain walls and bastions that testify to its long history of sieges and frontier warfare; a small museum interprets the site’s military history.

Built to control river approaches and regional communications, the fortress passed through Norwegian and Danish-Norwegian hands before being ceded to Sweden in the 17th century and later abandoned as a frontier fortification.

The ruins sit above the Göta älv near the town of Kungälv, north of Gothenburg, and are open to visitors seasonally with on-site interpretation.

• Founding and political transfer: Originally constructed in the early 14th century as a Norwegian border stronghold, the fortress was ceded to Sweden under the 1658 Treaty of Roskilde and later fell into ruin.

What to See#

• Ruins and ramparts: Remains of the medieval keep, curtain walls and bastions that illustrate the fortress’s former defensive layout; these ruins are accessible to visitors on foot.
• Visitor museum: A small museum and visitor information area near the site that interprets the fortress’s military history and the major sieges it endured.

Bohus Fortress is in Kungälv, about a 15-20 minute drive north of Gothenburg city centre. Regional buses serve Kungälv from Gothenburg; from the town centre the fortress is a short taxi ride or a 30-40 minute walk.

• Walk the outer curtain walk for the best overview of the fortifications and landscape toward the Bohuslän coast.
• Wear sturdy shoes - the site's stone steps and grassy slopes are uneven and can be slippery after rain.
• Visit in late afternoon for warm light on the granite and fewer coach-group appearances.
