Gamla Stan or the Old Town, is one of the largest and best preserved medieval city centers in Europe. The city was founded on this site in 1252.
The whole area, including the adjacent island of Riddarholmen are pedestrian-friendly, full of sights, attractions, restaurants, cafés, bars, and places to shop. It's also popular with lovers of handicrafts, curiosities and souvenirs. Narrow winding cobblestone streets, large buildings painted in many shades of gold and other bright colours, give Gamla Stan its unique character.
One of the most popular attractions in the area is the Royal Palace, one of the largest palaces in the world with over 600 rooms. There are several interesting museums with the palace building, including the Royal Armory, which has a collection of royal costumes and armor. The parade of soldiers and the daily changing of the guard is definitely worth watching.
