  We report relevant results from NA48 experiment at CERN SPS. NA48 was
proposed in 1990 \cite{proposal} to study direct CP violation in $K^0\to\pi\pi$
to a level of accuracy sufficient to resolve the inconclusive status left by
the previous measurements performed by NA31 \cite{NA31} and E731 \cite{E731}.
In 2002 NA48 published the final result \cite{NA48epsoeps}. Small modification
to the experimental setup have allowed NA48 to go forward with an extensive
investigation of $K^0$ rare decays and hyperon decays. Some results are already
available and reported here together with the final CP violation measurement.
