Nylars Round Church

Nylars Round Church is the best preserved of Bornholm's four medieval round churches, standing whitewashed and defiant above the fields of the island's gentle southern coast. Built around 1160, it belongs to a small family of fortress-churches unique to Bornholm, where the round form served God on Sundays and the community in times of danger, offering shelter from Baltic raiders during the turbulent Middle Ages.

The building rises in three storeys around a massive central pillar. The ground floor is the church proper, its low vaults and thick walls giving a hushed, cave-like calm. Around the central column runs the church's greatest treasure: a band of frescoes painted about 1250, the oldest surviving wall paintings on Bornholm. On a blue ground edged with red and yellow they tell the story of Creation and the Fall — Adam and Eve, the serpent, and the expulsion from Eden — in a naive, deeply human style that has charmed visitors for centuries. Above the nave, reached by a narrow stair inside the pillar, lies the upper defence storey, once a refuge and store; its ring of small openings let defenders watch the surrounding land.

Two runestones stand in the porch, reused as ordinary building blocks by the medieval masons. Both date from the late Viking Age and carry inscriptions in memory of the dead, a reminder that Christianity here was only a few generations old when the church was raised. The conical roof, rebuilt over the centuries, gives Nylars its characteristic silhouette, unmistakable from the road.

Nylars remains a living parish church, so visitors are asked to be quiet and respectful, especially around service times. Entry is free, though a donation towards upkeep is appreciated. Inside, information boards in several languages explain the frescoes and the church's defensive past, and the cool interior is a welcome pause on a warm cycling day.

The church sits about eight kilometres east of Rønne, the island's main town, and is easily combined with a wider tour of the round churches — Nyker, Olsker and the largest, Østerlars — which together make one of Denmark's most rewarding architectural circuits. The surrounding village is small and peaceful, with a couple of places to buy coffee in season.

Allow around three quarters of an hour to take in the frescoes properly, read the runestones, and climb, if you are able, toward the defence storey. Late spring through early autumn is the finest time, when daylight floods the whitewashed walls and the island's roads are made for slow exploration. For anyone drawn to medieval art, Viking heritage, or simply beautiful, strange buildings, Nylars is an essential Bornholm stop.
