Het Anker is one of the oldest continuously operating breweries in Belgium and the only one based inside Mechelen's medieval centre. The 90-minute guided tour runs through the working brewery — copper kettles, the modern fermentation hall, the bottling line — and ends with a tasting of the Gouden Carolus range: the dark, raisin-rich Classic, the strong tripel, the Easter beer, and the cuvée matured in their own whisky casks.
There is also an attached café-brasserie and a small hotel inside the brewery complex, useful if you plan to do the tasting properly. Tours run several times a day and should be booked in advance.
