Ušće Tower was built in 1964 as the headquarters of the Central Committee of the League of Communists of Yugoslavia.

Even today many people still call it "CK", which is the acronym for Centralni Komitet (Central Committee).

[5] In 1979, the Tower became a target of Nikola Kavaja, who hijacked American Airlines Flight 293 with the intention of crashing the plane into the building.

During the collapse of Yugoslavia in the 1990s, the Socialist Party of Serbia occupied the first ten floors of the building.

[6] On April 21, 1999 NATO air strikes hit the building, setting the upper floors on fire.

Two additional floors were added—conference halls are located on 24th and a restaurant on the 25th[8] The multimillion-dollar project has 25 stories (above ground), totaling around 25,000 m2 of office space.

The winning project was a design by architect Branislav Redžić, who envisioned a multi-functional urban center which would consist of two towers and a shopping mall.

[6] After years of announcing it, MPC Properties, another Matić's company, revealed in January 2018 that the construction of the new tower, next to the old one, will commence in February.

[11] At the time of opening, Ušće was the largest shopping mall in Belgrade by floor area, and the most visited one.

In sheer size, though not in number of visitors, it was surpassed by the Galerija Shopping Mall in Belgrade Waterfront in October 2020.
