The Large Magellanic Cloud (LMC) is an irregular satellite galaxy of the Milky Way, which has been observed extensively in Very-High-Energy (VHE) gamma rays with the H.E.S.S. telescopes since 2004 and reaches now a total observation time of 280 h. The exposure of the LMC is rather inhomogeneous, the region around the Tarantula Nebula having an exposure of up to 220 h while the exposure in the outer parts of the LMC is as low as 5h.

A search for point-like sources was performed on this data set. This search resulted in the detection of the four already known sources (N 157B, N 132D, 30 Dor C and LMC P3) but no further significant emission was revealed. Based on catalogues of pulsars, supernova remnants and high-mass X-ray binaries upper limits on the gamma-ray flux of these objects were derived.

In this talk updated results on the known gamma-ray sources as well as upper limits on the non-detected objects will be presented. It will be shown that for a large part of the LMC the existence of VHE gamma-ray sources with a similar luminosity as the already known sources can be excluded.
