Pantheon belongs on a map of ancient Roman sites because it is the named temple and church at Piazza della Rotonda, 00186 Roma RM. Its identity and visit pattern set it apart from the Colosseum, Forum, and Palatine cluster. Rather than adding it to a shared Forum-Palatine ticket assumption, treat it as a distinct central-Rome stop with its own rules.

The supplied access notes make this a useful planning contrast. The approach is mostly level over cobbles, unlike the steep and uneven sections noted for Palatino and the uneven paving of Foro Romano. Admission is separate from the Colosseum, and visitors should verify official hours, worship closures, and ticket rules. The possibility of worship closures is particularly important: a nearby address does not guarantee that a visit can be fitted in without checking the current conditions.

The map allows 45–60 minutes, giving Pantheon a shorter role than the Forum-Palatine area and a different rhythm from the museum visit at Trajan’s Markets. That estimate should remain flexible, while current operational details must be rechecked. The significant distinction is not a claim about importance; it is the clear separation of a central temple-and-church pin from the connected archaeological admission context elsewhere on the map.
