Step onto the irregular cobblestones of Walplein, shaded by leafy horse chestnut trees and bordered by traditional whitewashed stepped gables. In the corner of this tranquil square stands Brouwerij De Halve Maan, where the Maes brewing family has crafted traditional Belgian ales on this very spot continuously since eighteen fifty-six, keeping artisanal brewing alive in the medieval urban core. Horse-drawn carriages trot regularly across the square, the rhythmic clatter of hooves on stone echoing off ancient facades and transporting listeners back to an era before motorized transport.

In medieval Bruges, beer brewing was not merely a culinary tradition but an essential public health safeguard, as urban canal water was heavily polluted and unsafe to drink. At its economic peak in the fifteenth century, the city boasted more than thirty independent breweries, all drawing water from deep wells and boiling malt with peat fuel, with brewers enjoying high prestige as guild aldermen.

In twenty sixteen, De Halve Maan made international headlines by constructing the world's first subterranean beer pipeline. Confronted with the problem of heavy tanker trucks damaging Bruges' fragile medieval cobblestone lanes, the brewery crowdfunded a three-point-two-kilometer polyethylene pipeline buried beneath the streets, pumping four thousand liters of fresh beer per hour directly to their bottling plant outside town without a single lorry entering the historic center.

The brewery's most famous ale is the blond Brugse Zot, meaning Bruges Fool. The nickname dates to fourteen eighty-eight, when the citizens of Bruges asked Habsburg Emperor Maximilian the First for permission to build a new asylum for the mentally ill. Maximilian dryly replied: Simply close the gates of Bruges, for you are already an entire city of fools, giving the city its proud humorous emblem.

Stroll through the southern corner of Walplein down Wijngaardstraat and cross the arched brick bridge leading into the whitewashed sanctuary of the Begijnhof.
