Understanding the nature of the Dark Matter is one of the biggest challenges in frontier science today. Astrophysical and cosmological observations provide strong evidences for its existence. The XENON1T dark matter experiment aims at finding direct evidence for the scattering of Weakly Interacting Massive Particles (WIMPs) with xenon target nuclei in an ultra-low background dual-phase time projection chamber detector located in the underground National Laboratory of Gran Sasso in Italy. I will review the technological aspects, summarize the detector performance, and report the first results from XENON1T.
