The second day is for the things you have to go inside — and Brussels charges for fewer of them than most capitals.
Day one
The one-day plan — the flea market, the upper city, the Grand-Place, and an hour of Art Nouveau.

Day two, morning — one collection
Pick by what you actually like:
- The Royal Museums of Fine Arts — Bruegel and the Old Masters downstairs, Magritte on a separate ticket. Ask what your ticket covers before paying.
- The Comics Art Museum — in a Horta warehouse, and the building is half the reason.
- The Horta Museum — if you booked. Timed entry, limited numbers, no photography.
⚠️ All three close on Monday.

Day two, afternoon — east
The Cinquantenaire park and arch, free, and the European Quarter next door — where the House of European History is free, serious, and open when the paid museums are not.

Day two, evening
Beer. Not a themed bar but an ordinary café — the list is long, the glasses are specific to the beer, and nobody will rush you.
How the closures fall
Put the paid museum on a day that is not Monday. Put the European Quarter on the Monday. The flea market fits any morning.
