The structure's central uplift is known as the Vredefort Dome. The impact structure was formed during the Paleoproterozoic Era, 2.023 billion (± 4 million) years ago. It is the second-oldest known impact structure on Earth, after Yarrabubba. In 2005, the Vredefort Dome was added to the list of UNESCO World Heritage Sites for its geologic interest.
Venterskroon is home to the Vredefort Dome Information Centre. The Vredefort Dome is the center of the Vredefort impact structure. This impact structure is the world's largest, oldest, and most deeply eroded complex asteroid impact structure in the world, and has been listed by UNESCO as World Heritage Site [ 2 ] [ 3 ]
The Vredefort Dome (satellite image pictured) is the impact structure, or astrobleme, created by a meteorite that hit the Earth around 2 billion years ago, releasing massive amounts of energy and causing devastating global effects. It is the oldest and, with a radius of 190 km (120 mi), the largest impact crater so far discovered on Earth.

While the Iron Dome combats incoming rockets and artillery weapons, David’s Sling protects against short- and medium-range threats, and the Arrow 2 and Arrow 3 systems stop ballistic missiles.
In fact, apart from the Witwatersrand outcrops (i.e. where these rocks are exposed at the surface) in the immediate vicinity of the Vredefort Dome, virtually all the other outcrops occur in an arc approximately 80–120 km from the centre of the impact crater, to the west, north-west, north and north-east.
