Raekastyypit

Raekastyypit is a classification system used primarily in the study of late medieval Scandinavian architecture. The term is derived from the Old Norse word for “stone” and the modern Finnish suffix meaning “type.” It categorizes coastal stone structures according to construction techniques, material provenance, and stylistic elements. The system was first articulated by architectural historian Aino Niemi in a 1978 monograph, which identified three primary categories: the “Berg” type, the “Korp” type, and the “Jar” type. Each type is distinguished by distinct masonry patterns, foundation methods, and defensive features.

The Berg type is found predominantly in southern Sweden and is characterized by thick cut-stone walls with minimal mortar. The Korp type, common in northern Finland, uses more finely dressed stone and features recessed gun ports. The Jar type, located along the Norwegian coastline, incorporates a mixed material approach, combining stone and timber framing. Scholars use the Raekastyypit framework to infer trade routes, local resource availability, and regional defensive strategies during the 14th to 16th centuries.

In contemporary research, the Raekastyypit classification helps conservationists assess the structural stability of ruins and informs restoration guidelines. It has also influenced comparative studies of ice-age stone tool usage in adjacent regions. Though the original taxonomy remains debated, its influence persists in Scandinavian architectural historiography and heritage management.
