- **Monument to the People’s Heroes:** A large granite obelisk in the center of the square dedicated to those who struggled and died in the revolutionary struggles of China in the 19th and 20th centuries.
- **Mausoleum of Mao Zedong:** Located to the south of the square, this mausoleum houses the embalmed body of Mao Zedong, the founding father of the People’s Republic of China.
