Cluster cores as observed with Chandra

We review recent results from Chandra observations of the X-ray bright cores of clusters of galaxies. We discuss the detection of ``cold fronts'' and their implication for thermal conduction, the interaction of cooling flow and radio source in the Perseus cluster and the dynamical state of the central region of A1795. The radial distribution of metals in A1795 and the azimuthal variation in metallicity in 4C+55.16 are presented.
