  The role of the quark condensate in low-energy QCD and its behaviour in
nuclear matter are discussed. Partial restoration of chiral symmetry, as
indicated by a reduction of the quark condensate in matter, could significantly
alter the properties of nucleons and mesons. Various signals of these effects
are discussed: enhancement of the axial charge of a nucleon, lepton pair
production and $\overline K$-nucleus attraction. (Talk presented at the Nuclear
Physics Study Weekend on Extreme States of Nuclei, Abingdon, October 1995)
