Chilpik is a Zoroastrian tower of silence standing on a hill above the Amu Darya river, about 35 kilometres south of Nukus. It consists of a circular stone wall enclosing a platform where the dead were exposed to birds of prey as part of Zoroastrian funerary rites. The tower dates to roughly the 1st to 4th centuries AD and is one of the best-preserved examples in Central Asia.
The site is reached by hiring a taxi from Nukus, which can be combined with a visit to other ruins in the area. The tower itself is a 15-minute walk uphill from the road, and the views from the top over the flat desert and the river below are extensive. There is no entrance fee and no facilities. Visiting at sunset, when the light turns the desert orange, is worth the extra planning.
