We have investigated the change of the structural and magnetic properties of EuNiO$_3$ with pressure (up to $\\sim$ 20 GPa) across its quantum critical point (QCP) using low-temperature synchrotron angle-resolved x-ray diffraction and $^{151}$Eu nuclear forward scattering of synchrotron radiation, respectively.
