Greenmarket Square is a historical square in the centre of old Cape Town, South Africa.
The square was built in 1696, when a burgher watch house was erected here. In 1761, the watch house was demolished and the Old Town House built in the site. This building functioned as the city hall for a while.
Over the years, the square has served as a slave market, a vegetable market, a parking lot and more recently, an informal flea market trading mainly African souvenirs, crafts and curios.
During the apartheid era, Greenmarket Square was often the focus of political protests, due in part to its proximity to parliament, as well as the ethnicity of its traders and shoppers.
