Introduction to GoldReefCity: Located in the south of Johannesburg, it is a theme park built on the site of an old gold mine. The park vividly reproduces the architecture of GoldReefCity during the gold rush boom from the late 18th century to the early 19th century. Reflecting the prosperity of the time, there were banks, post offices, police stations, restaurants, bars, etc. Visitors can ride an old-fashioned train that moves slowly with steam, tour ancient buildings, and go down 220 meters underground to see the actual gold mining operations at that time. It is also interesting to see the actual melting of gold and the process of casting gold coins. In addition, there are a variety of amusement facilities in the Golden City.
