Best Landmarks in Bornholm

Northern Europe's largest castle ruin crowns a dramatic clifftop on Bornholm's northwestern coast, commanding sweeping views of the Baltic Sea. Built in the late 13th century by Archbishop Jens Grand, this medieval fortress served as the island's administrative stronghold for over 450 years before its abandonment in 1743. Today, the restored ruins stand as Bornholm's most visited landmark, accessible 24/7 and entirely free to explore, complemented by a modern visitor center with exhibitions, café, and panoramic viewing terraces.

Rising above the tiny sea fortress of Christiansø, the Big Tower (Great Tower) is a 17th-century bastion turned lighthouse and cultural space. Built as part of Denmark’s oldest naval fortress, it once guarded Baltic trade routes and later guided ships with its beacon. After a careful renovation in 2017, the tower now hosts atmospheric exhibitions and events, while its upper levels offer evocative views over ramparts, red-roofed houses and the open Baltic Sea surrounding this remote island outpost.

Domen is a striking wooden-and-glass dome on Allinge’s seafront, created in 2012 for Denmark’s democracy festival Folkemødet. Set just above the Baltic on the former circus grounds, it now functions as a flexible cultural house, with a light-filled lounge, terrace and event hall for talks, concerts and community gatherings. Its modern, geometric architecture contrasts with Bornholm’s traditional houses, while large windows frame wide sea views that shift with the weather and seasons.

Ny Kirke is a 12th-century round church in the village of Nyker, approximately 7 km from Rønne on Bornholm. Built in Romanesque style with a distinctive round nave, central pillar, and Gothic porch, it is the smallest and youngest of Bornholm's four round churches. The church features remarkable medieval frescoes depicting the Passion, a 17th-century carved pulpit, and a Romanesque font imported from Gotland. Originally dedicated to All Saints, it remains an important example of medieval Danish ecclesiastical architecture.

Nylars Rundkirke is Bornholm's best-preserved round church, built around 1160 and dedicated to St. Nicholas. This fortress-like medieval structure features walls over two meters thick, stunning 12th-century Romanesque frescoes depicting the Creation and Fall of Man, and a distinctive central pillar. Originally serving both religious and defensive purposes, the church remains a masterpiece of medieval Scandinavian architecture and one of the island's most visited landmarks.

Hammer Odde Lighthouse marks the rugged northernmost tip of Bornholm, standing on the granite promontory of Hammerknuden just outside Sandvig. Built in 1895 as a companion to the higher Hammeren Fyr, this compact 12 m granite tower still guides ships in the Baltic with its characteristic two white flashes every ten seconds. Surrounded by heather, rock and sea views, it is a peaceful spot for walkers, cyclists and photographers exploring Bornholm’s dramatic north coast.

Rising above the harbor of Rønne on Bornholm, St Nicholas Church is the island’s largest church and one of its most recognizable landmarks. Rooted in a 13th‑century chapel and reshaped many times, today it is a classic cruciform Lutheran church with a distinctive western tower, granite floors, and historic fittings including a 14th‑century baptismal font and early modern furnishings. Quiet, atmospheric and central, it bridges seafaring tradition, island history and daily parish life.

Snogebæk Havn is the easternmost port on south Bornholm, a charming fishing harbor and vibrant tourist hub where white sandy beaches stretch for kilometers. This protected island harbor welcomes both local fishermen and visiting sailors, offering excellent facilities, diverse dining options, artisan shops, and outdoor activities. The harbor's historic smokehouse reflects its fishing heritage, while the town has evolved into a cultural meeting point featuring chocolate production, ice cream made from local ingredients, working artist studios, and the famous annual harbor festival.

Lilleborg is a striking medieval castle ruin perched atop a 16-meter rocky cliff in the heart of Bornholm's Almindingen Forest. Built around 1150 as a royal fortress by King Svend III Grathe, this 12th-century stronghold showcases Saxon architectural style and remains one of Denmark's oldest preserved medieval monuments. Though destroyed in 1259, the site offers atmospheric ruins, panoramic forest views, and a fascinating glimpse into medieval power struggles on the Danish island.

Hidden in the pine forest near Dueodde on Bornholm, Kanonstilling G3 is a massive unfinished German World War II coastal gun battery. Built in 1940 to control the southern Baltic, its concrete ring, bunkers and tunnels were meant to hold a gigantic naval gun that was never installed. Today the silent emplacements, mossy walls and dark corridors create a striking contrast with the nearby dunes and holiday cottages, offering a powerful, atmospheric glimpse into the island’s wartime past.
