After discovering a wide river flowing northwards, they consulted the maps at the back of their Bibles and decided that it was the Nylrivier (Nile river). They called the stream Nyl River and settled the town and called it Nylstroom in 1866. After discovering what they believed to be a ruined pyramid, they were convinced that they had found the Nile. It was in fact, a natural hillock, known to the locals as Modimolle. In March 1866, the district of Waterberg was created out of some of the districts of Rustenburg and Zoutpansberg with a landdrost established in Nylstroom. A Dutch Reformed Church was built in 1889 and is the oldest church in sub-saharan Africa north of Pretoria. It was also used as a hospital during the Second Boer War. The river is the Nyl River, a tributary of the Mogalakwena River. The first South African railway line reached Modimolle in 1898, connecting the town to Pretoria.
