Which ancient wonder was built from bronze plates around an iron-and-stone framework?

The Colossus of Rhodes was built from bronze plates around an iron-and-stone framework.

The enormous statue represented Helios, the sun god, and stood on Rhodes after the city’s successful defense against a siege. Its builders could not cast the entire figure as one piece, so they assembled it in sections.

Ancient descriptions indicate that iron and stone provided internal support while bronze plates formed the visible exterior. This method allowed the sculptors to create a monumental hollow figure rather than a solid bronze mass.

The statue’s exact pose and location remain uncertain. Later artistic images often show it straddling the harbor, but that arrangement would have been structurally impractical and is not supported by reliable ancient evidence.
