Once part of the Graaff-Reinet district and known as Bo-Zeekoeirivier. As the farming community grew, a community centre was needed and, in 1854, the 8 656ha farm, Petrusvallei, was bought for 33 333 Rixdollars (R5 000). The former owner asked that the proposed town be called Hanover as his ancestors came from the German city. Walk through town and discover old furrows and historic buildings.
