  We present direct imaging of magnetic flux structures in the anisotropic,
spin-triplet superconductor Sr$_{2}$RuO$_{4}$ using a scanning $\mu$SQUID
microscope. Individual quantized vortices were seen at low magnetic fields.
Coalescing vortices forming flux domains were revealed at intermediate fields.
Based on our observations we suggest that a mechanism intrinsic to the material
stabilizes the flux domains against the repulsive vortex-vortex interaction.
Topological defects like domain walls can provide this, implying proof for
unconventional chiral superconductivity.
