Rising from Copenhagen’s King’s Garden like a red-brick fairy-tale, Rosenborg Castle is Christian IV’s 17th‑century Renaissance pleasure palace turned royal treasury. Inside, richly furnished rooms chart 400 years of Danish monarchy, from the intimate Winter Room to the dazzling Knights’ Hall, while the vaulted basement guards the nation’s Crown Jewels and royal regalia. Compact yet opulent, it’s an atmospheric glimpse into Denmark’s royal past in the very heart of the city.

Rising above the cobbled heart of Copenhagen’s old town, the Round Tower (Rundetaarn) is a 17th‑century observatory and viewpoint built by King Christian IV in 1642. A broad, whitewashed spiral ramp winds gently up through the tower’s hollow core, passing the former university Library Hall, now a lively exhibition and concert space. At the top, an open-air platform offers 360‑degree views over church spires, rooftops and the Øresund on clear days, while the historic observatory dome recalls centuries of stargazing and scientific curiosity.

Set in the gentle countryside of southern Funen, Egeskov Castle is one of Northern Europe’s best-preserved Renaissance water castles. Moated red-brick towers rise from a lake, encircled by exquisite historic gardens, mazes and a vast park packed with family attractions. Inside the lived-in castle, richly furnished halls and Titania’s Palace dollhouse tell stories of Danish nobility, while surrounding barns hold vintage cars, aircraft and quirky museums. It is a full-day destination where heritage, play and nature blend seamlessly.

Ærø is a small, storybook Danish island in the South Funen Archipelago, known for its cobbled-town charm, bright beach huts, and gently rolling farmland framed by the Baltic Sea. Three compact towns—maritime Marstal, fairytale Ærøskøbing and working harbour Søby—anchor a landscape of cliffs, cycling lanes, beaches and centuries-old churches. With big skies, long light evenings and a relaxed, lived-in feel, it is as much a thriving island community as it is a holiday escape.

Marstal Søfartsmuseum on the island of Ærø is a richly packed maritime museum spread across several buildings near Marstal’s harbour. Over 37 exhibition rooms and around 1,500 m² tell the story of Danish seafaring from the 1600s to today, with more than 300 model ships, ship portraits, navigation gear and curiosities brought home from the seven seas. Full-scale ship interiors, a museum harbour with historic vessels and an engaging playground make it as compelling for families as for serious maritime buffs.

Voderup Klint is a striking stepped cliff on the south coast of Ærø, rising to around 33 m and stretching for roughly 3–3.5 km along the Baltic Sea. Here the island’s fertile fields drop abruptly toward the water in a series of natural terraces formed by ancient landslides, creating a dramatic green amphitheatre facing the sea. Marked paths lead across the protected area, offering sweeping coastal panoramas, birdlife, and quiet corners to sit, watch ships pass, and feel the wind off the archipelago.

Søbygaard is Ærø’s last ducal manor house, set in gentle countryside just outside the port town of Søby. This compact moated estate blends 16th–17th century history with a lively activity centre, Geopark Visitor Centre, family-friendly nature play and seasonal exhibitions. Visitors can explore the historic buildings, walk the ramparts, learn about Ærø’s geology and island life, and enjoy concerts and events in an intimate rural setting.

Standing sentinel at the northwestern tip of Ærø, Skjoldnæs Lighthouse is a handsome granite tower surrounded by sea on three sides and framed by a seaside golf course. Built in 1881 from finely cut Bornholm granite, the 22 m lighthouse offers sweeping views over the South Funen Archipelago and, on clear days, all the way to Germany and surrounding islands. Open around the clock for a modest fee, it is as much a place for quiet coastal walks and geology-rich shorelines as for sunset photos and stargazing from the lantern gallery.

Strung out along Ærøskøbing’s Vesterstrand, the colourful bath houses of Vestre Strandvej form one of Ærø’s most iconic seaside scenes. These small, privately owned wooden huts sit right on the sand, framed by shallow emerald water and wide West Baltic skies. Built from the 1920s and now protected as cultural heritage, they embody classic Danish beach culture and are perfect for slow strolls, photography, and sunset swims just outside Ærøskøbing’s historic centre.

A charming museum housed in Ærøskøbing's former poorhouse, showcasing an extraordinary collection of over 500 ships in bottles crafted by Peter Jacobsen, known as 'Bottle Peter'. Each intricately detailed vessel represents years of meticulous craftsmanship, with bottles sourced from around the world—from Alaska to Shanghai—shaped as everything from traditional glass to novelty forms like clowns and parrots. A unique celebration of maritime heritage and artistic dedication.
