The high angular resolution observations carried out with long baseline stellar interferometers provide information about the innermost regions of circumstellar environment of young stellar objects. In this talk I present recent results achived with VLTI instruments (V1647 Ori, EX Lupi and HD163296) and report about the progress of the 2nd generation instrument MATISSE.
