Extragalactic Astronomy is one of the new domains being successfully addressed by the new generation of optical long baseline interferometers. The recent results on the unresolved Seyfert 1 nucleus NGC4151 by Keck Interferometer team and on the partially resolved Seyfert 2 nucleus NGC1068 by VLTI team confirm our current understanding of the Active Galactic Nuclei phenomenology. Once an extra level in increased angular resolution is reached by new observatories (e.g., Optical Hawaiian Array for Nanoradian Astronomy or Overwhelmingly Large Array), it will become possible to study the Broad Line Region of Seyfert 1 nuclei. In this paper, we present key results that interferometry could obtain on the topic, how they compare to an existing technique - reverberation mapping, and we describe a new observational technique that will lead to a tomographic picture of this region.
