The structure of the low- and medium-spin levels of the ${}^{211}\mathrm{Po}$ nucleus have been studied with in-beam $\gamma$-ray spectroscopy with the ${}^{208}\mathrm{Pb}(\alpha ,n){}^{211}\mathrm{Po}$ fusion-evaporation reaction. The level scheme was further extended with levels of the configurations $\pi {\left(h_{9/2}\right)}_{2^{+}-4^{+}}^2\otimes \nu g_{9/2}$, $\pi {\left(h_{9/2}\right)}_{8^{+}}^2\otimes \nu g_{9/2}$, $\pi {\left(h_{9/2}\right)}_{2^{+}-4^{+}}^2\otimes \nu i_{11/2}$, $\pi {\left(h_{9/2}\right)}_{2^{+}-4^{+}}^2\otimes \nu j_{15/2}$, $\pi {\left(h_{9/2}{f}_{7/2}\right)}_{8^{+}}\otimes \nu g_{9/2}$, and $\pi {\left(h_{9/2}\right)}_{0^{+}}^2\otimes \nu {\left(g_{9/2}\right)}_{0^{+}}^2{\left(s_{1/2}\right)}^{-1}$. The single-particle neutron states $\nu d_{5/2}$ and $\nu s_{1/2}$ were also identified. Furthermore, a number of states feeding the low-spin structures were added.
