  X-ray spectroscopy of Seyfert 2 galaxies provides an excellent probe of the
circumnuclear environment in active galactic nuclei. The grating experiments on
both Chandra and XMM-Newton have now provided the first high resolution spectra
of several of the brightest Seyfert 2's. We present Chandra HETG data on
Markarian 3 and XMM-Newton RGS data on NGC 1068. In both cases, the spectra are
dominated by emission lines due to radiative recombination following
photoionization, photoexcitation, and fluorescence. There is no evidence for
any significant contribution from collisionally-heated gas.
