Skaramagas (also spelled Skaramangas; Greek: Σκαραμαγκάς) is a port town in the western part of the Athens agglomeration, Greece.

In 2002, the port became entirely owned by a German group of investors under the industrial leadership of Howaldtswerke-Deutsche Werft, which became a subsidiary of ThyssenKrupp in 2005.

[2] In 1973, the Skaramagas harbour was the scene of an experiment carried out by Greek scientist Ioannis Sakkas, to test whether or not it was possible for Archimedes to use focused sunlight as a "heat ray" to burn Roman ships during the Siege of Syracuse (214–212 BC).

This event is mentioned in ancient accounts but often doubted by modern historians.

In the 1973 experiment at Skaramagas harbour, 70 mirrors with a copper coating, such as were available in Archimedes' time, did focus enough sunlight to set on fire a plywood mock-up of a Roman warship at a distance of around 50 metres (160 ft).
