The study of quantum quenches had a vast contribution to our understanding of out-of-equilibrium dynamics and relaxation in closed many-body systems. The investigation of entanglement growth in a quench could shed light to various features of the underlying physics, in particular for integrable systems. However, most of the studies focus on setups where the system is driven far from equilibrium due to the inhomogeneity of the initial state. In my talk, I will present results for quenches where the time evolution operator is made inhomogeneous

by the presence of a localized defect. I will compare results on entanglement spreading across a conformal defect, obtained either by field theory or by a lattice realization of the defect.
