Ströbo hög, Ancient burial mound in Köping Municipality, Sweden

Ströbo hög is a burial mound at Köping in Västmanland, about 40 metres across and roughly 10 metres high, one of Sweden's largest great mounds of the same type as Anundshögen and Uppsala högar. It stands beside road 250 toward Kolsva, next to the Strö crown estate, in a wider archaeological area along the Köpingsåsen ridge with smaller mounds, grave fields and settlement sites.

The mound was probably raised in the Late Iron Age, around 500–600 AD, as indicated by finds from a burial ground south of the mound investigated in the 1930s. It lay beside the medieval Eriksgatan and the transport route to Bergslagen, next to the royal estate at Strö. In the 19th century much of the surrounding ridge was quarried away, but the mound was saved through the efforts of antiquarian Richard Dybeck.

Tradition recorded as early as 1667 holds that an oak hut guarded by a dragon stands inside the mound, where candles sometimes burn. For 150 years Walpurgis Night bonfires were lit on its summit. A giant from Dalarna is also said to have dropped the stones forming the mound here.

The mound sits alongside Highway 250 toward Kolsva and is visible from the roadside. The site is easy to reach and offers open access for visitors who wish to explore the area.

A legend first recorded in 1667 holds that an oak hut stands inside the mound, guarded by a dragon, with candles sometimes burning there. Another tale says a giant walking from Dalarna to Mälaren dropped gravel from a hole in his sack and gave up at Ströbo, forming the mound.
