During the early days of the colony end 1600s, farmers would come here with their ox carts loaded with produce to be sold. The Old Town House built in 1761 (still intact) was the center of the local administration. Nowadays green market is not longer green, but covered with stalls selling African handicrafts, garments, bags and what not. I did not find the vendors obtrusive. Yes, they want to sell things, but hey it is a market.
