Munkácsy originally had a double-ring basin structure, but most of the inner ring was buried when the basin was flooded with volcanic lava.
Only a few remnants of the ring poke up through the lava, although low ridges in the lava seem to trace out much of the rest of the ring's circumference.
[1] Munkácsy is one of 110 peak ring basins on Mercury.
[2] The name of the crater was adopted by the International Astronomical Union in 2009.
