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. Perched gracefully against a backdrop of rugged hills and adjacent to the picturesque Mutrah Corniche, the palace's striking façade is a feast for the eyes. You 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.

The rusty towers of Gas Works Park once converted coal and crude oil into gas. After running for half a century and being shut down in 1956, the plant is now the center of a green park on the coast of Seattle and nature is slowly regaining its territories by covering parts of the structure with layers of vegetation. A perfect location for a stroll and a view over Seattle's skyline.
