The 15 Best Attractions in Brussels

Brussels' 13th-century Gothic cathedral, where Belgian royals marry — twin towers, luminous stained glass, and a Grimbergen-style baroque pulpit, all free to enter. It celebrates its 800th anniversary in 2026 with special events. Quieter and more rewarding than its fame suggests; just avoid visiting during Mass.

The most beautiful square in Europe isn't hype here — a full enclosure of gilded 17th-century guildhalls around the Gothic Town Hall, UNESCO-listed and free, day and night. Yes it's packed, and the cafés on the square charge tourist prices. Come back after dark when the facades are lit; that's when it gets you.

The terraced garden between the old town and the royal quarter — the classic postcard view of the Town Hall spire, a geometric French garden, and Brussels' museum cluster on all sides. Free, open all hours, and where locals eat lunch on sunny days. It's a passage more than a destination, but the best one in the city.

Vast, hauntingly beautiful ruins of a 12th-century Cistercian abbey 40km south of Brussels — roofless nave open to the sky, gardens, even a small vineyard and abbey beer. It's the best half-day trip from the city and most tourists have never heard of it. You'll need a train plus a 15-minute walk, and it's €10 in.

One of Europe's oldest covered shopping arcades, opened in 1847, a glass-roofed neoclassical gallery lined with chocolatiers, cafes and boutiques. It's free to stroll through and a beautiful shortcut in the rain. The shops are upmarket and prices reflect the prime tourist location.

Brussels' most authentic and chaotic daily flea market, held every morning in the heart of the working-class Marolles district. Dealers spread everything from genuine antiques and vintage clothing to outright junk across the cobblestones — the thrill is in the hunt. Sunday mornings are the biggest and best, drawing both serious collectors and curious tourists. Arrive early for the best finds and watch your belongings in the crowd.

The world's largest collection of works by surrealist master René Magritte, housed in a neoclassical building on Place Royale. The museum spans three floors with over 200 paintings, drawings, and sculptures tracing his full career. Allow at least two hours to do it justice. Weekends draw significant crowds, so booking online in advance is strongly advised.

Leopold II's colossal Art Nouveau glass palace in the royal domain — a kilometre of heated galleries, the iconic Winter Garden dome, camellias and centenarian palms. The catch that defines it: open only about three weeks a year, mid-April to early May (17 April–10 May in 2026), tickets online only, around €7. Locals treat it as an annual pilgrimage.

One of the world's great musical instrument museums, housed in the spectacular Art Nouveau Old England building. Visitors use wireless headphones that automatically trigger audio samples as you approach each of the 7,000+ instruments on display — a genuinely clever and immersive experience. The rooftop café has some of the best panoramic views in Brussels. Families with children find it surprisingly engaging thanks to the interactive audio format.

A major ethnographic and natural history museum focused on Central Africa, housed in a grand colonial-era palace in Tervuren, a short tram ride from the city center. Reopened in 2018 after a decade-long renovation, it now grapples honestly with Belgium's colonial past while showcasing extraordinary collections of art, wildlife, and cultural artifacts. The surrounding park and ponds are beautiful in any season. The tram journey through the Forêt de Soignes is itself a pleasure.

The National Basilica of the Sacred Heart is a colossal Art Deco church, among the largest in the world, whose dome panorama gives one of the best views over Brussels. The basilica itself is free to enter. It sits away from the centre in Koekelberg, and there's a fee to take the lifts up to the viewing gallery.

The Belgian monarch's official palace, a grand neoclassical building overlooking the Parc de Bruxelles, whose opulent state rooms include the Mirror Room with its beetle-wing ceiling. Entry is free when open. The catch is it only opens to the public for a few weeks in summer (roughly late July to early September).

Brussels' giant 1958 World's Fair molecule — nine steel spheres you can ride escalators through, with city views from the top ball. Worth it once for the retro-futurist weirdness and the Heysel skyline, but expect queues and a €16 ticket for what's essentially a 90-minute visit. Closed for maintenance a few weeks each winter.

Brussels sits at the center of Belgium's rail network, so some of the country's best cities are quick, cheap day trips on SNCB/NMBS intercity trains from Bruxelles-Midi, Central, or Nord. Ghent is about 30 minutes, Antwerp around 45, Leuven roughly 25, and postcard-perfect Bruges about an hour, all with frequent departures so you rarely need to reserve ahead. Buy a standard ticket at the machine or app; just note that weekend and off-peak fares can be cheaper, and Belgian trains occasionally run late, so leave buffer for connections.

The famous peeing boy is 55cm tall and permanently ringed by disappointed tour groups — that's the joke, and Brussels is in on it. See him because he's free and 4 minutes from Grand Place, check the dressing calendar (he wears costumes half the year), then visit the GardeRobe museum for the genuinely charming part.
