Temple of Artemis on the island of Corfu probably has the oldest limestone-pediment of any ancient Greek temple. The central figure in the pediment is that of the Gorgon Medusa in the Knielauf ("kneeling-running") position between two panthers. The temple, one of the largest temples of its time, was a peripteral building with a width of 22.41 m and length 49 m facing in an eastward orientation so that light could enter the interior of the temple at sunrise.
The temple had a colonnade consisting of eight columns on both the front and back of the building, while the sides had seventeen columns each, and thought to be the first Doric temple exclusively built with stone. Within the temple was a rectangular cella 9.4 m wide and 34.4 m long, which was subdivided in three spaces by two rows of ten columns.
