[2][3] The Opera House station of HCMC Metro Line 1 also located in the square side of Đồng Khởi Street.

[4] In 1955, place Augustin Foray was renamed Lam Sơn Square by the South Vietnamese government,[5] and the Municipal Theatre became the National Assembly building.

Lam Sơn Square also housed the Brinks Hotel, the building used by the United States Army officers and was bombed by the Viet Cong in 1964.

Today, the site is occupied by the Park Hyatt Saigon Hotel, and a memorial to the bombing was erected.

The square's layout had little change until 2018, when the open space behind the theatre, previously used as a parking lot, was transformed into a landscaped garden.
