  Recent results on studies of exotic hadrons at the LHCb experiment are
summarised. These are the observation of new resonances decaying to J/$\psi
K^{+}$ and J/$\psi\phi$, evidence of a J/$\psi\Lambda$ structure and
observation of excited $\Xi^{-}$ states in the $\Xi_{b}^{-}\to J/\psi \Lambda
K^{-}$ decay and the study of $B_{s}^{0}\to J/\psi\pi^{+}\pi^{-}K^{+}K^{-}$
decays.
