However, despite its economic, cultural and military prowess, Srivijaya left few archaeological remains in their heartlands in Sumatra, in contrast with Srivijayan episode in Central Java during the leadership of Sailendras that produced numerous monuments; such as the Kalasan, Sewu and Borobudur mandala. The Buddhist temples dated from Srivijayan era in Sumatra are Muaro Jambi, Muara Takus and Biaro Bahal, however unlike the temples of Central Java that constructed from andesite stones, the Sumatran temples were constructed from red bricks.
