The Berlin Wall Memorial is the central memorial site of Germany’s division. Located directly at the former border strip in the Bernauer Straße is a 1.4-kilometre piece of the Berlin Wall with a border strip and watchtower. The Gedenkstätte memorial is the last remaining stretch of the Wall as it existed during the separation era, and it conveys an impression of how the border fortifications really looked. The Visitor Center and the Documentation Center with a viewing platform are located on the other side of the street that belonged to the western part of the city. The exhibition 'Border Stations and Ghost Stations in Divided Berlin' is shown inside the Nordbahnhof S-Bahn station.

For a relaxing day trip, take the train to the former fishing village of Cascais. Here you can stroll on the beautiful decorated streets, experience the lively fish auction held every afternoon next to the main beach, visit "Museu do Mar" to see the rich history of Cascais or take a refreshing walk along the coastal road to Boca do Inferno ("Mouth of Hell") where high waves crash into gigantic caves.

The city’s cathedral is the longest (and tallest!) church in all of Denmark, which houses several century-old frescoes. You should not miss the baptismal font resting on the four Evangelists with their human bodies crowned with symbolic animal heads.

Teufelsberg, an artificial peak in Grunewald, was formed from the rubble of World War II. It provides a sweeping 360° view of the city. During the Cold War, this location served as a key surveillance site for British and American intelligence agencies. Nowadays, it's a popular spot, especially on weekends, when guided tours offer a glimpse into its past, enhanced by striking street art galleries.
