We aim to characterize this population by using the L-Galaxies semi-analytical model applied on top of the high resolution Millennium-II merger trees. Our results predict $\\sim$10 wandering black holes with masses $\\sim$2 $\\times$ 10$^{3}$ M$_{\\odot}$ in a typical $z$ = 0 Milky Way galaxy, accounting for $\\sim$2$\\%$ of the total non-stellar black hole mass budget of the galaxy. We find that the locations of these wanderers correlate with their formation scenario.
