In this chapter, we describe how the IceCube Neutrino Observatory transformed a cubic kilometer of natural ice at the geographic South Pole into a neutrino telescope. The concept of using the neutrino as an astronomical messenger is as old as the neutrino itself, and the challenge to open this new window on the high-energy universe was technological in nature. We discuss how IceCube was constructed and how the detector operates, including some detail on the 5,484 optical sensors that comprise the array. We highlight some of the primary results of the experiment, including the discovery of a diffuse flux of high-energy neutrinos reaching us from the cosmos, the observation of the first high-energy neutrino sources in the sky, and the observation of our Galaxy in neutrinos.
