A recent study in pre-Hispanic northern Peru shows previously unacknowledged use of adobe brick building as early as 5,000 years ago. What’s more, these adobe bricks were created by annual El Niño floods. Recently published in PNAS, the geoarchaeological research was conducted by Peruvian and American professionals based on discoveries in a remote forested region in northern Peru. The paper demonstrates that the earliest known standing adobe brick architecture in the Andes dates to around 5,100 calendar years B.P. (before present). Furthermore, the research shows how the adobe blocks were cut from compacted clay deposits created by El Niño flooding events.
