The Grote Markt (Dutch, pronounced [ˌɣroːtə ˈmɑr(ə)kt] ⓘ, Aalsters: Groeite Mert; meaning "Big Market")[1] is the central square of Aalst, East Flanders, Belgium.

The square behind the Aldermen's House (on Kattestraat) and the connecting street to Hopmarkt and Nieuwstraat are also referred to as part of the Grote Markt.

[2] The Grote Markt witnessed many tragic events unfold during its history.

In 1524, the first female Protestant martyr Clara 't Roen was executed on the square.

More than two centuries later, in 1748, the outlaw and gang leader Jan de Lichte suffered the same fate.
