An iron anchor and a box have been discovered near one of the two South China Sea ancient shipwrecks where a Chinese archaeological investigation is ongoing.

Approved by the National Cultural Heritage Administration, a deep-sea archaeological team is conducting the first stage of investigations at the site of the No. 1 and No. 2 shipwrecks near the northwest continental slope of the South China Sea. The investigation will run from late May to early June this year.

The iron anchor and the box were discovered in the southwestern direction of the No. 1 shipwreck site, with a distance of about 50 meters between them.

The lower part of the iron anchor is in a semi-buried state, with two anchor claws exposed, and there is an iron ring at the top of the cylindrical anchor rod.

Preliminary measurements show that the iron anchor is about 1 meter long. The diameter of the anchor rod ranges from 0.1 meters to 0.15 meters, and the diameter of the iron ring at the top is about 0.2 meters.

Further research is required to determine whether this iron anchor belongs to the No.1 shipwreck. The box is preliminarily judged to be made of wood and in a semi-buried state, and the contents of it require further investigation.

The No. 1 and No. 2 shipwrecks, near the northwest continental slope of the South China Sea, were discovered in October 2022.

The relatively well-preserved shipwrecks contain a large number of cultural relics, clearly belong to a specific era, and possess important historical, scientific, and artistic value. The shipwreck discovery is not only a major breakthrough in China's deep-sea archaeology, but also a significant archaeological discovery on a global level.
