The Las Campanas Observatory (LCO) owned by the Carnegie Institution for Science has been established in Chile in 1969. Two telescopes were commissioned in the 1970s. The Swope 1-meter which began observations in 1971 and  the duPont 2.5-meter that started in 1977. Both telescopes are still routinely used  by Carnegie astronomers  and international collaborations. At the beginning of the 2000s the Carnegie Institution, University of Arizona, Harvard University, University of Michigan and Massachusetts Institute of Technology put in operation the twin 6.5 meter Magellan telescopes. With their excellent optical performances and the superb seeing conditions the Magellan telescopes are being recognized among the best ground based astronomical observing facilities. The success of the project inspired the construction of the 25 meter Giant Magellan Telescope, which is expected to see first light in the next decade. In my  talk I will report  on  the LCO telescopes current and future capabilities  and briefly present some of the research activity  at the observatory.
