AGN: the XMM-Newton (and Chandra) legacy

In this talk I will review the constraints on the Active Galactic Nuclei (AGN) structure model emerging from X-ray studies of nearby Seyfert galaxies. Some issues are still open after more then three decades of X-ray observations, such as the ultimate origin of the non-thermal continuum in AGN, or the nature of the accretion flow onto the supermassive black holes. In other fields, such as the distribution of gas in the nuclear environment, or its ultimate ionization source, we have been more successful, and significant advancements have come from high-sensitivity and high-resolution measurements performed in the last years by major space facilities such as XMM-Newton (ESA) and Chandra (U.S.). My focus will be primarily on the latter.
