Nguiu was founded in 1911 as a Catholic mission by Francis Xavier Gsell.
In 2010 Nguiu was renamed Wurrumiyanga, meaning the place where the cycads grow, by the Tiwi Land Council.

There are two Catholic schools in the town; Murrupurtiyanuwu Catholic Primary School, and Xavier Catholic College (Years 7-13).
