1 Dollar - Elizabeth II Lighthouse of Alexandria

Part of a miniature gold series issued by the Solomon Islands government around 2013 pairing British colonial currency authority with the Seven Wonders of the Ancient World. The Lighthouse of Alexandria — the Pharos — stood on the island of Pharos in Alexandria's harbor and is estimated to have reached between 100 and 140 meters, making it one of the tallest man-made structures of antiquity for centuries after its construction under Ptolemy II Philadelphus around 280 BC. It survived in diminished form until a series of earthquakes between the 10th and 14th centuries left it a ruin, with the final remnants eventually quarried for the construction of the Mamluk-era Citadel of Qaitbay.
