Hallgrímskirkja is an iconic part of Reykjavík's skyline and at 74.5 metres tall, it is one of the tallest structures in the country. The gigantic church on the hill was a controversial project, but Icelanders have come to embrace their monumental tower in all its brutalist glory. The concrete mountain which took over 40 years to construct was inspired by the unusual columnar basalt formations along Iceland’s coast. You can admire the building inside and outside, go to the top of the tower to catch the view or attend an organ concert. The church is named after Hallgrímur Pétursson — a 17th-century minister and poet who wrote the 'The Passion Hymns'. The book remains popular to this day.

Situated approximately 40 km north of Karlskrona, Kristianopel is a charming village that breathes life into a captivating history. Echoes of bygone eras of strife and conflict resonate through its streets, bearing witness to a time when the border between Denmark and Sweden converged in this very region. The sprawling city wall, stretching for kilometres with formidable bastions, not only served as a protective barrier for inhabitants but stands today as a tangible reminder of the once heavily fortified border. Founded in the early 1600s by Danish King Christian IV, Kristianopel holds the prestigious title of Scandinavia's first Renaissance city. In this historic village, visitors can explore small shops, inviting restaurants, and a popular café, immersing themselves in its vibrant ambience. For a breathtaking panoramic view, you can walk around parts of the mighty old city wall, offering a unique perspective that captures Kristianopel's timeless allure.

The many winding steps of Charlotte Amalie were built in the mid 1700s. The bricks for the steps were brought all the way from Denmark as ballast in the empty hulls of the sailing ships. The picturesque 99 steps attract the most foot traffic and cameras. How could one resist this narrow stairway, adorned with flowers on both sides! The original name if the street can be translated as the Greater Tower Street. The steps lead to the Blackbeard’s Castle — a 17th century watch tower. The tower has been closed to visitors since Hurricanes Irma and Maria, but the view from up above is still stunning.
