Direct imaging of the "shadow" cast by the black hole event horizon and the test of physics in strong gravity is one of the important goals in modern astronomy. The ongoing Greenland Telescope (GLT) project in Academia Sinica Institute of Astronomy and Astrophysics (ASIAA) is devoting itself to this exciting area. By a future telescope in Greenland and the Very Long Baseline Interferometry (VLBI) technic, the major goal of the GLT project is to observe the shadow of M87 with a resolution (~20 micro arcsec) high enough to resolve the its event horizon. An overview of GLT project will be presented in this talk. (The GLT project is a collaborative project between ASIAA, Smithsonian Astrophysical Observatory, MIT Haystack Observatory, and National Radio Astronomy Observatory.)
