In traditional Taiwanese architecture, the style of the roof ridge and eave end on the rooftop is mainly characterized by "swallowtail" and "ridge head" designs. The "swallowtail" refers to the curved upward end of the ridge, splitting into two branches, while the eave end is designed to fit snugly against the "upper road" of the roof ridge, primarily used in main halls and important spaces. The "ridge head," also known as "Khoo-thâu," "Gô-thâu," or "ridge cap", is sometimes referred to as "horseback" by certain scholars. It is characterized by a bulging and convex joint where the eave end meets the roof ridge.
The Cultural Heritage Craftsmanship Workshop has planned a 15-day training program for Han-style tile making in this year. The program includes theoretical and practical courses, with the practical course focused on the "swallowtail ridge" design as the main topic. Building on the "Dieh-Dou" timber frame practiced in the 2023 Han-style Wooden Construction Class, the "swallowtail ridge" will be the primary practical subject in this tile work class. Skilled traditional craftsman and preservers of important techniques are invited to serve as instructors to guide the participants in mastering the craftsmanship of the "swallowtail ridge."
By engaging in the imitation of traditional Han-style tile making and the construction of "swallowtail" roof ridges, the participants will acquire skills in preserving and restoring traditional Han-style tile works, which can be applied to the restoration work of cultural heritage sites.
