The structure of the doubly magic ${}_{50}^{132}$Sn${}_{82}$ has been investigated at the ISOLDE facility at CERN, populated both by the ${\beta }^{-}$decay of ${}^{132}$In and ${\beta }^{-}$-delayed neutron emission of ${}^{133}$In. The level scheme of ${}^{132}$Sn is greatly expanded with the addition of 68 $\gamma$-transitions and 17 levels observed for the first time in the $\beta$ decay. The information on the excited structure is completed by new $\gamma$-transitions and states populated in the $\beta$-n decay of ${}^{133}$In. Improved delayed neutron emission probabilities are obtained both for ${}^{132}$In and ${}^{133}$In. Level lifetimes are measured via the Advanced Time-Delayed $\beta \gamma \gamma$(t) fast-timing method. An interpretation of the level structure is given based on the experimental findings and the particle-hole configurations arising from core excitations both from the N = 82 and Z = 50 shells, leading to positive and negative parity particle-hole multiplets. The experimental information provides new data to challenge the theoretical description of ${}^{132}$Sn.
