the honden, is missing. It is believed shrines of this type are reminiscent of what shrines were like in prehistorical times. The first shrines had no honden because the shintai, or object of worship, was the mountain on which they stood. An extant example is Nara's Ōmiwa Shrine, which still has no honden. An area near the haiden (hall of worship), sacred and taboo, replaces it for worship. Another prominent example of this style is Futarasan Shrine near Nikkō, whose shintai is Mount Nantai. For details, see Birth and evolution of Shinto shrines above. Shinmei-zukuri is an ancient style typical of, and most common at, Ise Grand Shrine, the holiest of Shinto shrines. It is most common in Mie prefecture. Characterized by an extreme simplicity, its basic features can be seen in Japanese architecture from the Kofun period (250–538 CE) onwards and it is considered the pinnacle of Japanese traditional architecture. Built in planed, unfinished wood, the honden is either 3×2 ken or 1×1 ken in size, has a raised floor, a gabled roof with an entry on one of the non-gabled sides, no upward curve at the eaves, and decorative logs called chigi and katsuogi protruding from the roof's ridge. The oldest extant example is Nishina Shinmei Shrine. Sumiyoshi-zukuri takes its name from Sumiyoshi Taisha's honden in Ōsaka. The building is 4 ken wide and 2 ken deep, and has an entrance under the gable. Its interior is divided in two sections, one at the and one at the with a single entrance at the front. Construction is simple, but the pillars are painted in vermilion and the walls in white. The style is supposed to have its origin in old palace architecture. Another example of this style is Sumiyoshi Jinja, part of the Sumiyoshi Sanjin complex in Fukuoka Prefecture. In both cases, as in many others, there is no veranda. Taisha-zukuri is the oldest shrine style, takes its name from Izumo Taisha and, like Ise Grand Shrine's, has chigi and katsuogi, plus archaic features like gable-end pillars and a single central pillar (shin no mihashira). Because its floor is raised on stilts, it is believed to have its origin in raised-floor granaries similar to those found in Toro, Shizuoka prefecture. The honden normally has a 2×2 ken footprint (12.46 × 12.46 m in Izumo Taisha's case), with an entrance on the gabled end. The stairs to the honden
