St. Isidore Ranch Teshphon

Located within Seong Isidore Ranch, this unique arched structure is a rare example in Jeju of the Teshphone architectural style. Teshphone architecture began in Ireland and uses a semi-cylindrical concrete construction method, reflecting the site’s history as it was once used at Seong Isidore Ranch as livestock barns and storage space. Today, rather than being an interior experience venue, it draws many visitors as a representative photo spot in western Jeju thanks to its distinctive exterior blending with the ranch’s wide grasslands. Surrounded by expansive pastures, stone walls, and ranch trails, it’s ideal for a leisurely walk. Each season offers a different mood—from vivid green fields to silver grass, and the calm scenery of winter. It’s one of western Jeju’s must-visit 감성 (sentimental) spots, especially when visited together with Seong Isidore Ranch’s Milk Stand and the ranch trails.
