This railway and pedestrian bridge is one of the most recognisable spots in Cologne, and hard to miss if you’re near the Cathedral. Originally built in the early 1900s, it was rebuilt after being blown up in 1945. These days, most people come for the view and the thousands of love locks clipped to the railings. It’s a short, easy walk across the Rhine with some great photo angles of the city, especially at sunset.

Although no tours are offered inside Al Alam Palace, the building, which serves as the ceremonial residence of Sultan Haitham bin Tariq is still a must-see on your Muscat itinerary.

Visitors can wander around its grounds to marvel at its intricate exterior and lush gardens. Adding to the grandeur, the palace is flanked by two imposing 16th-century forts, Al Mirani and Al Jalali.
