What ancient Roman complex is adjacent to the Colosseum? The Roman Forum is adjacent to the Colosseum.

The Colosseum stands just east of the Roman Forum, the central civic and political complex of ancient Rome. The Forum contained temples, basilicas, government buildings, monuments and public meeting spaces, making it one of the city’s most important urban areas.

The Colosseum was built in the valley between several hills, on land that had previously been part of Nero’s imperial estate. Construction began under Emperor Vespasian around AD 72 and the amphitheatre opened under Titus in AD 80. Its placement connected spectacular entertainment with the political and religious heart of Rome.

The nearby Palatine Hill is another defensible answer to “near the Colosseum” in a broad geographic sense, but it is a hill rather than the ancient Roman complex normally intended by this question. The Roman Forum is the canonical answer; it is often visited together with the Colosseum and Palatine Hill as one archaeological area.
