The latest results on classical and exotic spectroscopy obtained by the LHCb Collaboration studying proton-proton collisions are presented. These include studies related to both conventional states, namely mesons and baryons, and exotic ones, notably tetra and pentaquark structures. The Λ+ c → pK−π+ amplitude analysis with Λ+ c polarisation measurement, the observation of new excited Ω0 c and Ξ0 b baryons, and the study of charmonium contributions in B+ → J/ψηK+ are introduced. Regarding exotic states, the study of χc1(3872) production, the T + cc tetraquark observation and the evidence of a new pentaquark state are presented. These new results extend the striking series of hadrons discovered and analysed by the LHCb Collaboration.
