Lattice gauge theory is the theoretical framework where the dynamics of strongly interacting particles can be investigated starting from the fundamental equations and keeping track of all systematic and statistical errors. Lattice QCD is bound to make it possible an unambiguous and precise comparison between theory and experiment. After an introduction to the subject, I focus on recent conceptual, technical and algorithmic advances which have paved the way to study quantitatively the spontaneous and the anomalous breaking of chiral symmetry in Quantum Chromo Dynamics from first principles. Emphasis is given to the recent results for the spectral density of the Dirac operator and for the topological susceptibility.
