The invention discloses a hidden viscous damper energy-dissipation shock-absorption device for wooden structure ancient building column foots. The device comprises a cylindrical foundation stone, an annular groove with a center column as the circle center is formed in the top of the foundation stone, an annular clamping groove is formed in the annular groove, and a plurality of viscous dampers ofa same structure are annularly distributed along the annular clamping groove. An annular clamping groove steel disc is connected to the tops of the viscous dampers in a covering mode, a plurality of expansion bolts penetrate through the annular clamping groove steel disc, and the tops of the expansion bolts are wedged into a wood column above the expansion bolts. While the original appearance of an ancient building is not damaged, the damping device is additionally arranged in the foundation stone under the column, and energy of seismic waves can be effectively consumed and reduced. Double breakthroughs are achieved in the aspects of building appearance maintenance and earthquake resistance.
