The complex contained 614 rooms, seven restaurants, a health club, a 750-seat showroom and a 60,000 sq ft (5,574.2 m 2) casino, all on a narrow 2.6 acres (1.1 ha) plot of land next to Caesars Atlantic City. The property opened as Harrah's at Trump Plaza on May 14, 1984.

Trump would oversee the construction, while Harrah's would operate the property, referred to as Harrah's Boardwalk, after opening. Harrah's, the gaming unit of Holiday Inn, joined as a partner a month later. The Trump Organization, a company owned by real estate developer Donald Trump, began construction of the casino in June 1982. Its main tower was demolished by controlled demolition on February 17, 2021. Designed by architect Alan Lapidus, it operated from May 14, 1984, until September 16, 2014. Trump Plaza was a hotel and casino on the Boardwalk in Atlantic City, New Jersey, owned by Trump Entertainment Resorts. That particular casino was closed three years later with plans to reopen a larger resort in its place in a time predicted to be Atlantic City’s comeback.Septem 9 years ago ( September 16, 2014) The purchases led Trump and those in charge to believe that things were turning around in Atlantic City so THCR opened Trump’s World Fair in 1996. The company took over Trump Plaza and purchased the Taj Mahal. In 1995, Trump established the Trump Hotel and Casino Resorts (THCR) as a publicly-traded company. Underfunded, it was seen as a venture doomed to fail. Just one year later, the Taj Mahal was forced to go into Chapter 11 bankruptcy, Trump Plaza and Castle following suite in 1992. However, since he won the unfinished Taj Mahal from talk show host Merv Griffin, total debt on the casino exceeded $820 million. Seen as the crown jewel of Atlantic City, it brought in visitors from all over the world, including many celebrities. This $1 billion project, opened in April 1990, was New Jersey‘s tallest building (at 42-stories) and one of the world’s largest casinos. Next, he began one of biggest projects of his career: opening Trump Taj Mahal.
