Alkaline-earth atoms in optical lattices have emerged as a powerful platform for precision measurements, quantum simulation and quantum computation with neutral atoms. We present a setup combining techniques developed for optical atomic clocks and quantum gas microscopes, thus marrying high frequency resolution with microscopic spatial resolution. We demonstrate single-site and single-atom resolved fluorescence imaging of individual strontium atoms in a large and homogeneous cavity enhanced optical lattice. To prepare a two-dimensional system we optically address a single layer of the optical lattice on the ultra-narrow 1S0-3P2 transition. The required high spatial resolution is achieved by application of a magnetic field gradient and precise engineering of lattice light shifts. We perform high resolution fluorescence imaging of single atoms by employing a two color imaging scheme. Narrow-line sideband cooling suppresses heating and allows to maintain low temperatures during the imaging process.
