Neutrino oscillations are described by a mixing matrix connecting the weak and the mass eigenstates of the three neutrino flavours. It contains three mixing angles, θ12, θ23, θ13, from which θ13 has only recently been determined by oscillation experiments both at reactors and accelerators. The talk presents these experiments, focussing on the reactor experiment DoubleChooz and the accelerator experiment T2K. Combining the results from reactor and accelerator experiments yields sensitivity on the CP-violating parameter δCP of the lepton sector. Finally, expectations on future sensitivities on the neutrino oscillation parameters are briefly summarized.
