I think this area at first was invaded by impacts about as the Moon's south pole, but later lava covered the area, leaving a smooth plateau, namely Mare Imbrium and Mare Frigoris. Lava however, failed to cover the higher areas, such as the crater Plato, high region around it called Montes Alpes, and peaks Mons Pico, Montes Recti and Montes Teneriffe.
The crater Plato (109 km), I think it was magnificent before being flooded. I imagine how it would look deeper and maybe even with inner terraced walls and a central peak. All these features have disappeared beneath magma that came to hide the old relief. After the area was flooded by lava, other impacts have occurred that led to the appearance of some small craters on Mare Imbrium and Mare Frigoris like crater Bliss (20 km), or Plato D (10 km), B (13 km) or E (7 km).
Info Plato crater.
