The historic fair of Sant'Ambrogio around the Sforza Castle
The Oh Bej! Oh Bej! Fair is the most traditional and popular event of the week of Sant'Ambrogio, Milan's patron saint. Its origins date back to the 13th century, and for over five centuries, on the days around December 7th, the city gathers around the Sforza Castle and Parco Sempione, in Piazza Castello (Municipality 1), amidst sweets, surprises, and objects of all kinds.
The curious name Oh Bej! Oh Bej! — meaning "Oh beautiful! Oh beautiful!" in Milanese dialect — is said to be the joyful exclamation of children upon receiving gifts and sweets at the fair. The tradition is deeply linked to the figure of Sant'Ambrogio and has marked the start of the Christmas festivities in the city for centuries.
The fair brings together hundreds of stalls offering crafts, sweets, toys, flowers, books, antiques, modern collectibles, and local products. It is the realm of winter street food — roasted chestnuts, sweets, mulled wine — and traditional Christmas shopping, away from standardized commercial circuits. Strolling among the stalls, against the backdrop of the illuminated Sforza Castle, is an experience that is part of every Milanese person's Christmas identity.
The fair is held concurrently with the Feast of Sant'Ambrogio and other events of the patron saint's week, from the mass in the basilica to the opening night of La Scala opera house. Admission is free, and the atmosphere is unmistakably that of the beginning of Milanese winter: an event that draws citizens and visitors from all over Lombardy and has marked the start of Christmas in Milan for centuries.
The 2026 edition of the Oh Bej! Oh Bej! Fair is expected in the days leading up to Sant'Ambrogio's Day, on December 7th, approximately from December 4th to 8th, 2026, around the Sforza Castle and Parco Sempione.
As per tradition, hundreds of stalls will offer crafts, sweets, toys, flowers, books, antiques, and local products, in a Christmas atmosphere that kicks off the city's festivities. Definitive dates and times will be confirmed by the Municipality of Milan closer to the event.
