We present a kinematic analysis of the double-barred early-type galaxy NGC 357. The radial velocity and velocity dispersion profiles along both the nuclear bar axis and the semi-major axis clearly reveal the presence of the two bars. The results indicate that the bulge is pressure supported whereas the |vr|/σ ratio shows a plateau along the nuclear bar.
