  We present preliminary results from high resolution (~ 0.05") adaptive optics
observations of Cygnus A. The images show a bi-conic structure strongly
suggestive of an obscuring torus around a quasar nucleus. A bright (K'=18.5)
point source is found near the expected position of the nucleus. We interpret
this source as the hot inner rim of the torus seen through the opening of the
torus. Using high angular resolution K-band spectroscopy, we measure the ratio
of molecular to recombination hydrogen lines as a function of distance to the
center of the putative torus. These measurements place constraints on the
properties of the torus and indicate a projected diameter of ~600 pc.
