The LHCb experiment at LHC is a multipurpose detector in the forward region with a special focus on heavy--flavour physics. Designed as a single-arm forward spectrometer covering the pseudorapidity range $2 < \eta < 5$, \lhcb can provide vertexing, tracking information, particle identification (PID) of charged particles and energy measurement. During LHC Run 1 (2010-2012, centre-of-mass energy 7 and 8 TeV) and Run 2 (2015-2018, centre-of-mass energy 13 TeV), the LHCb experiment recorded proton-proton collision data corresponding to 9 $fb^{-1}$.
This is one of the largest collected samples of heavy-flavour decays with proper PID information, making LHCb an ideal place to study charm spectroscopy. These proceedings present three recent charmed hadron properties and spectroscopy studies at \lhcb: observation of Cabibbo-suppressed two-body hadronic decays and precision mass measurement of the $\Omega_c^0$ baryon, observation of new \Omegac states decaying to the $\Xi_c^+ K^-$ final state and the first determination of the spin-parities of the \Xic$(3055)^{+(0)}$ baryons.
