Bohus Fortress

A lot of Nordic history has been played out right here, at Bohus Fortress. On our motorhome journey along Trollhätte canal and the Göta River, the fortress felt like an obvious stop.

Bohus Fortress is located on the Göta River, in the south-eastern part of Kungälv, about two kilometres north of Gothenburg.

On the road to Bohus Fortress: Lilla Edet

On the way from Trollhättan to Bohus Fortress, we followed the Trollhätte Canal and the Göta River to Lilla Edet, where the sixth and final lock in the canal system is located. Like the previous locks, this is of course a lock that can accommodate enormously large boats.

Sweden's oldest lock

Lilla Edet is also home to Sweden's oldest lock, which is no longer in use. Construction of the lock began in the 1580s and the lock was completed in 1607, as Sweden's first lock. Nearby there is also a memorial stone in memory of 47 soldiers from the Västgöta-Dal regiment who drowned after putting out the great fire in Lilla Edet in August 1830.

Visiting Bohus Fortress

After the visit to Lilla Edet, we continued south to Bohus Fortress, a drive of about half an hour. We had not Lucky with the weather, but there's no such thing as bad weather, only bad clothes ... or was it? We put on our rain gear and walked up to the fortress in the pouring rain.

The visit costs 100 SEK/adult and the castle turned out to be bigger than we first thought. You walk from one courtyard to the next, and new staircases, tower rooms, cellars and exhibitions are constantly appearing. Normally (when it's not raining) there also seems to be plenty of outdoor activities for children.

Bohus Fortress - on Norway's southernmost border

The area around the mouth of the Göta River is an old Nordic borderland, where Norway, Denmark and Sweden once met. The old Norwegian town of Kungahälla was Norway's southernmost outpost.

In the early 14th century, a power struggle broke out between King Birger of Sweden and his brothers, Dukes Erik and Valdemar. Erik was married to the Norwegian princess Ingeborg, and therefore had strong ties to Norway. His marriage gave him access to the castle of Ragnhildsholmen, located on an island opposite Kungahälla.

Erik and Valdemar soon controlled large parts of western Sweden, and the conflicts led to historic events such as the 'Håtuna Games' and the 'Nyköping Feast' in Nyköpingshus. Neither king wanted Erik and Valdemar to have too much power, and the Norwegian king Haakon V Magnusson tried to withdraw Ragnhildsholmen castle. When Erik refused, a siege of the castle began.

According to the Swedish Erik Chronicle, it was Count Jacob Nielsen who in 1308 urged the King of Norway to build a fortress on the high cliff where the Göta River divides. Now Bohus took over as Norway's southernmost outpost.

The 'Bahusian bang'

Bohus Fortress has been through many sieges, but the most famous must be the one known as the 'Bahusian Battle'. In 1566, the Swedes took the fortress, and it went so well that they even managed to raise the Swedish flag on the Red Tower. Then one of the Norwegians chose to sacrifice his life and crawled under the tower with gunpowder. The Swedes died instantly and the siege was a failure.

Bohus Fortress became Swedish

At the Peace of Roskilde in 1658, Bohuslän became Swedish, and thus Bohus Fortress became part of Sweden. However, this did not mean that peaceful times awaited. The worst siege ever took place in the summer of 1678, when 15 000 Danes and Norwegians subjected 800 Swedish and Finnish defenders to massive attacks over two months.

At the last moment, Swedish reinforcements arrived and the enemy had to surrender. The fortress was now largely destroyed, and it was rebuilt without regaining its former glory. It was later mostly used as a prison, but it was realised that an unguarded fortress could do more harm than good and in 1789 it was decided that the fortress would be demolished.

Prison with dark dungeons

In addition to its important role in defence, Bohus Fortress has also served as a prison for almost 500 years. Here, prisoners could spend long periods of time in dark dungeons with no daylight. Other punishments could include shame or corporal punishment, or even the death penalty.

How did I (Helena) end up in that pillar of shame? I don't really know, but luckily I was able to get out after a while and could look at the fortress.

If you find it interesting to immerse yourself in different old, horrible methods of punishment, you can stand for a while and read the different descriptions. You can also look down into one of the dungeons, and feel very grateful for your freedom when you leave.

One of those imprisoned at Bohus Fortress was the priest Thomas Leopold, who was imprisoned for a total of 43 years (32 of which were spent in the fortress) because of his faith. He refused to repent and died in the fortress at the age of 77. His cell still exists and can be visited.

Activities in the fortress

Inside the fortress grounds there is a small pond, which you can cross by pulling yourself across with a small rope ferry. Due to the rain, the fortress was not too crowded, but the ferry was still popular.

We also saw that there are a lot of other activities, such as bouncy castles, horseshoe pitching and archery. Certainly popular when it's less wet!
