Researchers analysed 138 dispersed blocks from a dismantled sector, using geometric silhouettes and computational matching, to propose how the early Inca walls fitted together.
Why it matters: It sheds new light on the polygonal masonry that precision-stonework researchers focus on.

A Science news feature reports that Andean archaeologists are replacing the traditional Inca chronology (empire from 1438) with radiocarbon dates. At Saqsaywaman, dated charcoal suggests the site began to be remodelled with fitted masonry around 1400, with construction peaking from about 1418; the first results are in press at Antiquity.

20 Jul 2026 · Dahshur, Egypt
Xavier Landreau, Guillaume Piton and Sayed Hemeda used satellite imagery, 19th-century maps and watershed mapping. They argue that two 600–700 m structures across Wadi Dahshur, west of the Red Pyramid, long read as stone-transport ramps, are dams, one with a duckbill-shaped spillway, linked to a roughly 1 km diversion channel passing close to the pyramid.
