The stadium is next to Union Station in the city's Downtown West neighborhood,[1] and was completed in November 2022, ahead of the 2023 MLS season.

One of the locations surveyed had previously been intended for a stadium for the St. Louis Rams before the team moved back to Los Angeles.

[2] On February 17, an exploratory group of local businessmen calling itself "MLS2STL" formed with the goal of bringing an MLS franchise to St. Louis.

[3] On November 18, a proposal for a $200 million stadium, to be built on 30 acres (12 ha) of land owned by the Missouri Department of Transportation, was unveiled.

[11] A competing prospective ownership group, Foundry St. Louis, offered to pay the $80 million public portion if they were allowed to join SC STL's bid for MLS expansion.

[13] The project was endangered in January 2017 when Alderwoman Christine Ingrassia withdrew the proposal to put the $80 million public contribution to a vote.

"[15] By the end of January, the St. Louis Board of Aldermen revised the stadium bill, this time with a public contribution reduced to $60 million.

[23] On October 9, 2018, the group "MLS 4 The Lou" announced a new proposal to build a soccer-specific stadium on the same land next to Union Station.

[28] The bid met all of the criteria put forth by MLS, including a solid financial backing, local government support, a strong soccer fan base, and a downtown Soccer-specific stadium with access to public transit.

Energizer, a St. Louis-based company that manufactures batteries, signed a naming rights agreement for an undisclosed fee and length of time.

Along with the naming rights, the club announced a new premium seating section in the stadium, presented by Energizer to deliver an 'immersive fan experience'.

[39][40] The stadium features a grass pitch 40 feet (12 m) below street level, surrounded by two tiers of seating totaling 22,423 seats (with the ability to add an additional 2,500), topped with a clear plastic awning to keep out weather while keeping in crowd noise and avoiding disrupting shadows on the pitch.
