We analyse the spatially-resolved stellar populations of 9 local ($z<0.1$) Brightest Cluster Galaxies (BCGs) observed with VIMOS in IFU mode. Our sample is composed of 7 slow-rotating and 2 fast-rotating BCGs. We do not find a connection between stellar kinematics and stellar populations in this
text block small sample. The BCGs have shallow metallicity gradients (median $\Delta$[Fe/H]~$= -0.11\pm0.1$), high central metallicities (median $[$Fe/H$]_{[\alpha/Fe]=0}= 0.13\pm0.07$), and a wide range of central ages (from 5 to 15~Gyr). We propose that the reason for this is diverse evolutionary paths in BCGs. 67 per cent of the sample (6/9) show $\sim 7$~Gyr old central ages, which reflects an active accretion history, and 33 per cent of the sample (3/9) have central ages older than 11 Gyr, which suggest no star formation since $z=2$. The BCGs show similar central stellar populations and

However, massive early-type galaxies from ATLAS$^{3D}$ have consistently old ages (median Age~$=12.0\pm3.8$~Gyr). We also
