Results of the ultra deep survey of the Large Magellanic Cloud (LMC), performed with the INTEGRAL observatory, are presented. The large exposure ~7 Ms spent by the observatory in 2003-2012 observing this region allowed us to detect more than twenty sources: ten belonging to the LMC itself (7 HMXBs, 2 PSRs, 1 LMXB), six of extragalactic origin and others owning to other galaxies from the Local Group -- the Milky Way and Small Magellanic Cloud. Four new hard X-ray sources were discovered during the survey in addition to IGR J05414-6858 reported by us earlier; two of them were identified with distant AGNs. We report also for the first time the detection of hard X-rays from the Crab-like pulsar PSR J0537-6910 and identification of the hard X-ray source IGR J05305-6559 with the high-mass X-ray binary EXO 053109-6609.
