Near-infrared high-resolution imaging and spectroscopic observations of NGC 7469, Mrk 231, IRAS F10214+4724, and Circinus are presented. They indicate the presence of extended star-forming activity in the vicinity of the active nuclei of these galaxies on scales between 10 pc and 1 kpc from the nuclei. The very different distance scales covered by these objects show that the coexistence of AGN and star-formation activity is a common phenomenon. A first-order evolving star-cluster model calculation shows that we are beginning to understand the history and evolution of these circumnuclear star-forming regions.
