Brussels Sights Worth the Trip
Brussels packs a UNESCO square, a retro-futurist atom and one of Europe’s great surrealist collections into a city small enough to cross on foot. The trick is timing it right, because several of the best sights only open on their own schedule.
Start at the Grand-Place, go back at night
The Grand-Place is free, open 24/7, and genuinely worth two visits: once by day to take in the Baroque guildhalls, once after dark when they’re lit gold and the crowds thin out. If you want the interior, the Town Hall runs 55-minute guided tours of the aldermen rooms and council chambers for €15 per adult, book ahead through visit.brussels, since there’s no independent self-guided access and the tower isn’t open for casual climbs.
Ride up into the Atomium
The Atomium (Metro 6 to Heysel) is Brussels’ most photographed structure: a 102-meter model of an iron crystal magnified 165 billion times, with six of its nine spheres open via escalator and a top-sphere observation deck at 92 meters. Adult tickets are €17, seniors 65+ pay €15, students and children over 115cm pay €9, and under-115cm is free, the ticket also gets you into the adjacent Design Museum Brussels. Open daily 10:00-18:00, last entry 17:30. Book Atomium tickets ahead of time on GetYourGuide to skip the queue at the base.
See the Magritte collection
The Royal Museums of Fine Arts at Mont des Arts hold both the Magritte Museum (230 works, €13 adult, €10 senior, €5 for ages 18-25, closed Mondays) and the Old Masters Museum (Bruegel, Rubens, Van Dyck, €13 adult). A combined ticket for both runs €20 adult, €15 senior, €8 youth, and the permanent collections are free on the first Wednesday of every month from 13:00. Both are included on the Brussels Card.
Catch the Royal Palace during its short window
The Royal Palace of Brussels only opens to visitors in summer, and only just reopened at all: after a three-year restoration closure (2023-2025), it’s back for 3 July to 16 August 2026, €10 per adult (ages 13+), with mandatory advance online booking and no walk-ins. Closed Mondays, plus occasional extra closures around state visits, check dates before you plan a trip around it. Confirm current Royal Palace visiting dates on visit.brussels .
The other stops worth the ticket
The Musical Instruments Museum (MIM), set in the Old England Art Nouveau building, holds over 1,200 instruments with infrared audio guides included, €15 adult, closed Mondays, with a rooftop restaurant that has one of the best views in the city. The Cathedral of St. Michael and St. Gudula is free to enter for the main nave; the Romanesque crypt is €1 and the treasury €2.
Set your expectations right
Manneken Pis is 61cm tall, go in knowing that so you’re not underwhelmed. The Atomium sits 25 minutes north of the center by metro and needs a genuine 1.5-2 hours, so don’t try to squeeze it into a half-day alongside everything else. If you want to base yourself walking distance from the Grand-Place, check central Brussels hotel rates on Booking.com .
