Visiting Brussels is never dull, whether you are after architecture, culture, gastronomic discoveries or simply having a good time. Being home to many institutions of the European Union, Brussels is often called the Capital of Europe and is a pleasant combination of a busy city atmosphere and a relaxed vibe.

Situated in the picturesque Grand Place square, the Town Hall of the City of Brussels is a pearl of Gothic architecture that makes your visit hard to forget. While strolling through the old town streets, add a local flavour to your trip and taste the Belgian fries and some of the most sought-after craft beers in the world. To sweeten your visit, go for the Belgian waffles or chocolate, the country's most famous product.

If you wish to enrich your day with art, the Belgian Royal Museum of Fine Arts is the place to go. Looking for panoramic views over Brussels? Head to Atomium, one of the most prominent landmarks of Brussels, and see where unique architecture meets surrealistic experiences. And don’t forget the Manneken Pis ("little pee man" in Flemish), the most photographed landmark in Brussels, it’s almost become customary to take a selfie with it. 

This city has many faces and does not cease to please its visitors, so check out Icelandair's flights to Brussels BRU and plan your vacation now!
