# The Ships That Sailed Out of the Stone

*At Tanum, one of Europe’s most studied prehistoric landscapes, surveyors find sixteen carved rock surfaces nobody had recorded*

## In brief

- Surveyors found 16 previously undocumented carved rock surfaces at Tanum’s Trättelanda area
- The largest panel measures at least 11 by 10 metres and holds well-preserved ships and human figures
- The survey is led by the Foundation for Documentation of Bohuslän Rock Carvings with Vitlycke Museum
- Tanum joined UNESCO’s World Heritage List in 1994; over 600 rock-art sites lie in the 41-sq-km property
- The main Tanum carving tradition is dated roughly 1700 to 500 BC; the new panel is not yet dated

The granite of Bohuslän has been walked over for a hundred and fifty years by antiquarians, professors, schoolchildren and UNESCO inspectors, and it has been counted among the most thoroughly read stones on earth. Yet the stone keeps secrets. At Trättelanda, at the southern edge of Sweden’s Tanum World Heritage landscape, a new inventory has uncovered 16 carved rock surfaces that no earlier survey had documented — among them a great panel, at least 11 by 10 metres, crowded with ships and human figures of what the team called exceptional preservation.

## A survey that began and immediately paid

The work is led by the Foundation for Documentation of Bohuslän Rock Carvings, in cooperation with Vitlycke Museum, and it has only just begun. That is what makes the tally remarkable: not one stray carving added to the record, but sixteen surfaces surfacing at once, at the very start of the survey, inside a landscape examined for generations. The foundation called the largest panel a fantastic new discovery, and its edges are not yet defined — the decorated rock may extend well beyond what has been recorded so far.

Tanum lies in northern Bohuslän on Sweden’s west coast. UNESCO placed it on the World Heritage List in 1994, citing the density, variety and preservation of its carvings. More than 600 known rock-art sites lie within the roughly 41-square-kilometre World Heritage property; across northern Bohuslän as a whole, at least 1,500 carving sites are known. Their imagery runs to humans, animals, weapons, symbols — and, above all, ships.

## When the sea stood higher

The ships are the signature of this coast. Some are simple outlines; others carry rows of crew, or join complex scenes of weapons, animals and ceremony. They were carved when the landscape was another country entirely. During the Bronze Age, higher sea levels brought shorelines and waterways close to rocks that today look out over fields and farmland. Communities cut their vessels onto stone that stood near the water, and archaeologists read them not as pictures of boats but as fragments of a whole visual world: movement, status, warfare, belief, the long negotiation between people and the sea.

The new Trättelanda panel has no firm date yet. But it sits within a tradition UNESCO places at roughly 1700 to 500 BC, the great age of the Nordic Bronze Age carvers. The geology made it possible. When the Scandinavian Ice Sheet retreated some 14,000 years ago, it left broad faces of smooth granite, and prehistoric artists returned to those canvases again and again, pecking and grinding images into the stone across generations.

## Vitlycke, the Spear God, and now Trättelanda

Some panels became archives. The famous Vitlycke panel runs more than 20 metres and holds roughly 500 carvings — ships, people, animals, scenes that scholars still argue over. At Litsleby, a 2.3-metre human figure known as the Spear God stands over a crowd of ships thick with crew. Now Trättelanda adds another substantial surface to the density, its full dimensions unknown, its individual figures still awaiting documentation.

There is a lesson here about what a heritage list protects and what it merely presumes. Tanum has been studied, photographed and praised for generations, and yet sixteen surfaces lay outside the documented record until someone walked the ground systematically and looked. The stone did not move. Only the looking was incomplete. Work at the site continues, and the surveyors have reason to think the Bronze Age has not finished giving up its ships.
