The first measurement of coherent photoproduction of rho0 mesons in ultra-peripheral Pb-Pb collisions at the LHC is presented. The invariant mass and transverse momentum distributions for rho0 production are studied, and the production cross sections is measured with and without requirement of nuclear break up. The cross section is compared with model predictions and with results from lower energies.
