4 World Trade Center (The Southeast Plaza Building)
118ft tall, 9 floors.
4 WTC opened in 1975, slightly later than its almost identical siblings buildings 5 & 6, and was located directly next to the South Tower.
4 World Trade Center was one of the low rise buildings surrounding the World Trade Center plaza, a fairly nondescript building especially compared to its 110 story neighbors, but it did hold some secrets.
4 World Trade was the main street level entrance to the mall at The World Trade Center, the largest indoor shopping mall in Manhattan, and was also home to Gemellis' a large bar and restaurant.
The top 2 floors of 4 World Trade Center were home to home to one of the largest commodities exchanges in the country, with hundreds of millions of dollars changing hands here every day, trading everything from wheat to cotton, coffee to oil and metals.
The basement of 4 World Trade Center also housed vaults used to store gold and silver bullion. Published articles about precious metals recovered from the World Trade Center ruins in the aftermath of the 9/11 attack mention around $300 million worth of gold was recovered.
The main orange juice trading scene at the end of the 1983 Eddie Murphy and Dan Aykroyd film Trading Places was filmed inside one of the large trading floors on the 8th and 9th floors of 4 World Trade Center.
The building used a similar construction method to the towers themselves, with a central core and load bearing exterior columns (albeit fewer of them).
