A coastal centre with more than one identity

Stenungsund is a working coastal town where the archipelago, a busy transport corridor and heavy industry share the view. From the centre, boats and the water's edge point toward Tjörn and Orust; inland, the four tall power-station chimneys have become a landmark of the industrial era. This is not an old fishing village preserved in amber. The municipality says that fishing existed here long ago but never became the main livelihood; the town instead changed repeatedly, from agriculture and maritime trade to summer resort, regional shopping centre and petrochemical hub. Statistics Sweden counted 14,381 residents in the mapped statistical built-up locality, or tätort, Stenungsund, on 31 December 2023. SCB region 1415TC104 describes the continuous urban locality, not the entire municipality with its other settlements and countryside.

The centre makes a practical base for everyday services and for reaching the islands. Shops and the harbour edge are close together, and the municipality's Kulturhuset Fregatten combines a library, gallery, cinema, café, workshop space and children's science activities under one roof. The town therefore has a mixed rhythm: commuters and local errands in the morning, a working port and industrial landscape in the background, then a walk beside the water or a bus onward to a coastal excursion.

From the old village of Stenung to a resort

The municipality traces the name to Stenung, a medieval village south of Vetteberget near today's Stenungeby and Mariagården. The name appears in writing in 1388, with other spellings in later records. Linguists have proposed that it might mean a village below the mountain, but the municipality presents that as one interpretation, not a proven etymology. The surrounding landscape contains passage graves, stone cists, cairns and rock carvings, evidence of much older settlement than the surviving written name.

During the eighteenth- and nineteenth-century herring periods, salting and fish-oil works processed large catches along the coast. When the herring declined, agriculture again dominated household livelihoods, while the narrow sound between the mainland and Stenungsön helped the settlement grow as a trading place. In the nineteenth century, affluent families—many from Gothenburg—built summer villas on Stenungsön with private jetties and bathing houses. The opening of the Bohusbanan railway in 1907 brought more visitors and helped turn the area into a seaside resort. The resort era faded in the 1940s, but later transport and rising prosperity encouraged second homes.

Stenunge by offers a small, tangible link to that older rural pattern right in the centre. Two timbered farmhouses, Mariagården and Västergården, and traces of the former cultivated landscape remain from the medieval village. Mariagården dates to the late eighteenth century; Västergården is dated broadly to 1770–1790. Both are protected buildings, but Västergården remains a residence, so visitors should treat the site as a heritage setting rather than assume every interior is open. A reconstructed hand-built watermill evokes the stream-powered milling that the municipality says is likely to have existed here, while the precise earliest mill history remains uncertain.

Bridges, industry and the town's present-day economy

The bridges linking Tjörn and Orust to the mainland opened in 1960. They reinforced Stenungsund's role as a commercial centre serving the surrounding communities as well as local residents. The same decade brought a more radical transformation. After a power station was decided on in 1954 and built from 1956, the Nordic region's first cracking plant began operating here in July 1963. Petrochemical companies expanded around the port, changing the skyline and the area's employment base. The power station was completed in 1969. These dates explain why the industrial chimneys sit so prominently in views toward the islands; they also help set the older bathing-town story beside the newer industrial one.

Today, the economy mixes petrochemical production and logistics with retail, public services, education, hospitality and marine activity. The port and central shopping areas serve a wider coastal hinterland, while the nearby rail line and E6 corridor connect the town to Gothenburg and the northern Bohuslän coast. The municipality's civic and cultural services remain part of this central-place role; Fregatten's exhibitions and events are a useful counterpoint to the industrial view.

Walk beside the water, then choose an island or forest route

For an easy urban walk, follow Kvarnslingan through central Stenungsund between the stream in Solgårdsdalen and the Kvarnberget dam, or take the municipality's five-kilometre Hälsans stig loop. On Stenungsön, the Södra Stenungsön nature reserve combines conifer-mixed forest, rocky shoreline and bathing coves. The municipality's longer marked walk is 3.3 kilometres and passes the Stora Huvudet viewpoint above the road tunnel toward Tjörn Bridge; a shorter path of about two kilometres runs south from Hawaii bathing place. Paths and shoreline conditions can be slippery or exposed in wet or windy weather, so bring suitable footwear and check local notices.

For a more wooded day out, Bottenstugan in Svartedalen is the starting point for several signed loops and sections of Bohusleden, with lengths ranging from short lake circuits to longer forest walks. Nearby Tjörn and Orust are reached over the bridges that made Stenungsund a regional gateway, but they are separate destinations rather than part of the town itself. Regular trains on Bohusbanan stop at Stenungsund, and buses link the centre with the region; exact frequencies and replacement transport vary by date. Confirm Västtrafik schedules, trail access, bathing conditions, and the opening programme at Fregatten before setting out.
