Originally a medieval castle called Kastello, it was destoyed in 1856 and resurrected in 1939. Now, it's the crown jewel of the Old Town. Inside, ancient mosaics bedeck the floors, and you'll find a unique collection of 16th and 17th-century Western furniture. On a hot day, the castle's massive walls provide a much-needed reprieve from the heat.

Gamla Stan, Stockholm's historic Old Town, is a fascinating district that transports visitors back in time with its cobblestone streets, medieval architecture, and rich cultural heritage. Strolling through Gamla Stan's narrow alleyways, you'll come across a treasure trove of well-preserved buildings, including the iconic Royal Palace and the renowned Storkyrkan Cathedral. The neighbourhood's charming squares, such as Stortorget and Järntorget, are adorned with colourful facades and brimming with cosy cafés, traditional restaurants, and charming shops. Gamla Stan also offers an array of museums and cultural attractions.

Many of the most popular museums and attractions are situated on the island of Djurgården, which is also part of the Royal National City Park. This picturesque island provides an ideal setting for leisurely strolls, invigorating jogs, scenic cycling routes and paddling adventures, as well as a lovely spot for a picnic. In addition, Djurgården has loads of restaurants and sightseeing options. If you're travelling with children, Djurgården is a must: here you'll find the city's best attractions for children, all within walking distance of one another.
