Readers interested in traditional African cultures may enjoy the African Vernacular Architecture Database. This database was started in 2014 by Jon Twingi Sojkowski, an architect based in South Carolina whose passion for traditional African architecture began when he was a Peace Corps volunteer in Zambia. Visitors to this resource will find a diverse collection of crowdsourced photographs showing traditional architecture in every country in Africa. The photos are organized by country and include (for example) homes, granaries, barns, and religious buildings all built using indigenous techniques and local materials. The database also includes a "special collection" of early 1900s postcards depicting African vernacular architecture, and those who are in or have visited Africa are encouraged to submit their own relevant photos. According to Sojkowski, traditional construction forms and methods in Africa have begun to be passed over in favor of Western ones, and the African Vernacular Architecture Database is "the only on line [sic] source to view images and descriptions from every African country."
