Indirect evidence of traditional Austronesian architecture, however, can be gleaned from their contemporary representations in art, like in friezes on the walls of later Hindu-Buddhist stone temples (like in reliefs in Borobudur and Prambanan). But these are limited to the recent centuries. They can also be reconstructed linguistically from shared terms for architectural elements, like ridge-poles, thatch, rafters, house posts, hearth, notched log ladders, storage racks, public buildings, and so on. Linguistic evidence also makes it clear that stilt houses were already present among Austronesian groups since at least the Late Neolithic.
