Last century saw large farms in Hainaut brewing barley and hops. Silly is a village lying in the Ath, Enghien and Soignies triangle and is crossed by the Sylle, the river from which the village takes its name. Silly possesses a brewery that was founded in 1850 as Cense de la Tour, and that is today operated by the 5th generation. From 1947 the Brewery became more prominent than the farm yet was still only producing top fermentation beer like Grisette, Saison and Scotch. Several years later in 1950 when the Brewery already had a chain of bars, it began producing a bottom fermentation beer Pils as part of its product range.
