Until now, more than 70 active galactic nuclei, nearly all blazars, have been identified as emitters of gamma rays at very high energies (TeV), by means of Cherenkov telescope networks like the HESS experiment in Namibia. The spectral and temporal information collected from these sources allows to better understand the extreme conditions in the region of emission. The main tool for linking observations to the physics of the sources is the modelisation of spectral distributions incorporating models of radiative transfer. I will present recent observations in this domain and I will discuss their interpretation with leptonic and hadronic models. Projections for CTA will also be discussed.
