Saaihalle, Medieval wool trading hall in Bruges, Belgium

Saaihalle is a medieval trading building in Bruges featuring Gothic architectural style with a distinctive gabled roof and intricate brick patterns on its walls. The structure occupies a central position on the historic square where textile merchants once conducted their business.

The oldest part dates from 1399, when Genoa housed its commercial representatives here; a neighbouring consul's house in the Grauwwerkersstraat was added in 1441. After Bruges' economic decline from the late 15th century, the Genoese left and rented the building to private tenants. In the 17th century it passed to the saai weavers, who gave it the name Saaihalle.

The name Saaihalle comes from the light woolen cloth called saai, woven here by weavers who used the lodge from the 17th century. The building began as the Genoese lodge, housing commercial representatives from Genoa from 1399; other Italian cities such as Venice and Florence also kept agents in Bruges. A green sign above the entrance now reads "friet museum", marking the Frietmuseum that has occupied the building since 2008.

The Saaihalle stands at Vlamingstraat 33, on the former Beursplein, not beside City Hall. The Frietmuseum occupies the building since 2008; the entrance is the dark doorway under the green sign. The stepped gable and pointed-arch windows face the street, with the large round-arched window at lower right.

The facade bears the year 1399, making it the oldest building in Bruges with a construction date shown on its exterior. The Genoese lodge was later rented to weavers of light wool cloth called saaien, which gave the building its current name, Saaihalle.
