Gradually, native (animist) elements in Javanese culture became more prominent, and so the earlier Indian-style imagery and architecture gave way to a more overtly indigenous style.
One example of this change can be seen in the temple known as Candi Sukuh, which came at the end of the Hindu period in Javanese history (1437, according to an inscription).
The temple is built on a mountain, as is so often the case. Further, the temple itself resembles a miniature pyramidal mountain, with steps that allow one to ascend as one would a mountain.
