Curved blocks of marble that were incorporated into the Fortress structure, but are considered too intricately cut to have been quarried for that purpose, have been posited as the remnants of a marble base for the Colossus, which would have stood on the sandstone block foundation.[29]

Stone foundation and partially-reconstructed temple ruins at the apex of the Acropolis of Rhodes
Archaeologist Ursula Vedder postulates that the Colossus was not located in the harbour area at all, but rather was part of the Acropolis of Rhodes, which stood on a hill that overlooks the port area. The ruins of a large temple, traditionally thought to have been dedicated to Apollo, are situated at the highest point of the hill. Vedder believes that the structure would actually have been a Helios sanctuary, and a portion of its enormous stone foundation could have served as the supporting platform for the Colossus.[31]

Modern Colossus projects[edit]
In 2008, The Guardian reported that a modern Colossus was to be built at the harbour entrance by the German artist Gert Hof leading a Cologne-based team. It was to be a giant light sculpture made partially out of melted-down weapons from around the world.
