This book examines Inka stone masonry, a major hallmark of their culture, as a whole, from stone block extraction to drressing techniques, tool use and stone block transport. The Inkas' five most exploited quarries within the Cuzco region are examined with a special emphasis on the Llama Pit of Rumiqolqa Quarry. The main styles of wall construction are categorised and their application to different kinds of Inka buildings are examined. The implications of apparently earthquake-proof Inka walls are explored. Accompanied by a CD with 100 colour photographs of stone and walling detail with more general views of Inka sites.
