Which of the Seven Wonders of the Ancient World was built to celebrate withstanding a siege by the Macedonian leader Demetrius?

The Colossus of Rhodes was a statue of the Greek titan-god of the sun Helios, erected in the city of Rhodes, on the Greek island of the same name, by Chares of Lindos in 280 BC. One of the Seven Wonders of the Ancient World, it was constructed to celebrate Rhodes' victory over the ruler of Cyprus, Antigonus I Monophthalmus, whose son Demetrius unsuccessfully besieged Rhodes in 305 BC. Demetrius was a Macedonian Greek nobleman, military leader, and became king of Macedon (294–288 BC).

According to most contemporary descriptions, the Colossus stood approximately 70 cubits, or 33 metres (108 feet) high—the approximate height of the modern Statue of Liberty from feet to crown—making it the tallest statue of the ancient world. It was destroyed during the earthquake of 226 BC, and never rebuilt.

The statue stood for 54 years until Rhodes was hit by the 226 BC earthquake, when significant damage was also done to large portions of the city, including the harbour and commercial buildings, which were destroyed. The statue snapped at the knees and fell over onto the land. Ptolemy III offered to pay for the reconstruction of the statue, but the oracle of Delphi made the Rhodians afraid that they had offended Helios, and they declined to rebuild it.
