1

Botanical Garden

Welcome to the greenest corner of Copenhagen. This garden, part of the Natural History Museum of Denmark, has been at its current location since 1874. It is home to over 13,000 species of plants, but the real star is the white cast-iron and glass Palm House. Inspired by London's Crystal Palace, it was built in the 1870s and offers a tropical escape even in the depths of a Danish winter. As you wander through the rock gardens and around the lake, notice how the space feels both like a scientific laboratory and a romantic park. This was once part of the city's old fortifications, which explains the undulating landscape.

2

Rosenborg Castle

Rising before you is Rosenborg Castle, a masterpiece of Dutch Renaissance style. Built by King Christian IV in the early 17th century, it was originally intended as a summer residence outside the city walls. Today, it stands as a time capsule of royal history, housing the Danish Crown Jewels and the coronation chairs. The red brick and grey sandstone facade, topped with slender copper spires, is iconic to Copenhagen’s skyline. While the interior requires a ticket, the exterior views and the moat surrounding the castle provide a perfect backdrop for understanding the lavish lifestyle of the 17th-century Danish monarchy.

3

The King's Garden

Step into Kongens Have, or The King's Garden. This is the oldest royal garden in Denmark, established by Christian IV just before he built Rosenborg Castle. Once a private orchard and kitchen garden for the palace, it is now the city's most popular public park. Look for the 'Kavalergangen,' a beautiful tree-lined path that has hosted strollers for centuries. The garden is dotted with sculptures, including a famous one of Hans Christian Andersen. It’s a perfect spot to observe local life, as Copenhageners flock here for picnics and sunbathing whenever the weather permits.

4

Kastellet

Leaving the floral gardens behind, you arrive at Kastellet, one of the best-preserved star fortresses in Northern Europe. Constructed in 1626, its distinct pentagonal shape was designed for defense, with high earthen ramparts and a deep moat. Remarkably, this is still an active military site, though the ramparts are open to the public for walking. As you walk the perimeter, you'll see a traditional Dutch windmill and the bright red barracks known as 'The Rows.' The contrast between the rigid military history and the peaceful, grassy slopes makes Kastellet a unique experience in the heart of the city.

5

Gefion Fountain

Located just outside the entrance to Kastellet, the Gefion Fountain is the largest monument in Copenhagen. It depicts a powerful scene from Norse mythology: the goddess Gefion driving four massive oxen. Legend says she turned her four sons into these beasts to plow so much land from Sweden in a single day that she created the island of Zealand, where Copenhagen now sits. The fountain was donated by the Carlsberg Foundation to celebrate the brewery's 50th anniversary. The cascading water and the sheer scale of the bronze figures create a dramatic sense of movement and power.

6

The Little Mermaid

Finally, we reach Copenhagen's most famous resident. Perched on a rock at Langelinie pier, the Little Mermaid has been greeting visitors since 1913. Inspired by Hans Christian Andersen's fairy tale, the bronze statue was commissioned by Carl Jacobsen of Carlsberg. Despite her small size—standing only 1.25 meters tall—she has become the symbol of the city. She represents the melancholic ending of the original story rather than the Disney version you might know. Take a moment to look out at the harbor; this spot marks the end of our journey through the green and historic soul of Copenhagen.
