Borgring.
Harald Bluetooth’s ring fortress, four kilometres from the square: a circle about 145 metres across, built around 980, hidden in a field until 2014, on the UNESCO World Heritage list since 2023 — and since June 2025 with a museum of its own.

The fortress
A circle in a field.
Around 963 Harald Bluetooth decided that the Danes would be Christian; around 980 he built a ring of fortresses to hold his kingdom together. Borgring is one of them — a round rampart with two streets crossing at its centre and a gate where each street meets the ring, the same strict geometry as Trelleborg, Fyrkat, Aggersborg and Nonnebakken. Its gates burned, the fortress vanished, and the circle lay under a field outside Lellinge for a thousand years, until archaeologists traced it in 2014 with laser scanning and magnetic measurements.
On 17 September 2023 the five Viking-age ring fortresses were inscribed together on the UNESCO World Heritage list. In June 2025 the visitor centre opened beside the ring: the King’s Hall on Harald’s choice of faith, a UNESCO hall, the King’s Path out to the ring, a café with a view, a shop and a roof terrace. Today the ring is drawn on the ground in gravel paths, with timber gates at the ends of the streets — which is what the drone sees, and what the graphic above draws over it.
