H.E.S.S. has observed the very young supernova remnant SN1987A during 2003 in a search for TeV {gamma}-ray emission. These observations were taken during a build-up phase of H.E.S.S. with 2 operating telescopes, {approx}6400 days after the initial explosion. Preliminary analysis so far reveals no convincing evidence for TeV emission and the 99% upper limit is compared with a predicted light curve. The H.E.S.S. field of view encompasses a number of other interesting objects including the X-ray shell 30 Dor C, the Crab-like plerion PSR B0540-69, the SNR N157B, and the X-ray binary LMC X-1. These objects may be associated with several features seen in the H.E.S.S. skymaps at marginal significances, and further observations in 2004/2005 with 4 telescopes will be valuable for confirmation.
