Godavaya is located on the coast of Sri Lanka. Here Sri Lankan and German archaeologists excavate the old Kingdom of Ruhuna, gathering evidence of its glorious past. Excavations have been carried out since 1994, under Professor Helmut Roth of the University of Bonn in Germany, along with the Sri Lankan Archaeological Department, directed by Director General Dr. W. H. Wijeyapala, and the German Archaeological Institute (DAI). Recently they excavated the temple area of Gotha Pabbatha Rajamaha Vihara in Godavaya. The temple area was not only religious, but it was also used as an administrative centre during the reign of King Gajabahu I. A unique Brahmi inscription on a rock next to the ancient shrine room clearly states that this was indeed a significant sea-trading place. True to Sri Lankan tradition, Ahalaya, one of King Gajabahu's ministers, has immortalized himself by getting his name carved in an inscription on this rock. In ancient times, Sri Lanka was heavily involved in the sea trade and exported dark red garnets. Up to the 7th century AD, these semi-precious stones were found as burial objects as far away as European graves. New research has now revealed that most of those garnets were from India and Sri Lanka. Spices were also exported from the island. The dig has uncovered Sassanian (Persian) and Chinese pottery as well as Roman coins. Ships from the East carrying silk from China exchanged their commodities with merchandise from the West in the transit harbor of Godavaya, as trade ships from both directions usually did not go farther than Sri Lanka. Therefore, the Kingdom of Ruhuna played an important role as a trade center in early East-West trade. Godavaya was active in sea trade up until the 6th century AD. Along with trade items from Arabia and China, local articles of trade arrived via the local river. [h] The harbor town of Godavaya is mentioned in the Mahawamsa's chapter on "The 12 Kings". Even in early western books like the Topographia Christiana of the 6th century AD, Sri Lanka is referred to as an important sea trade centre on the Silk Route. Sri Lanka is also mentioned in The Periplus Maris Erythraei, a guide to trade on the Red Sea and India, write
