Sumiyoshi-Taisha is the only important structure to survive the Allied bombing raids of WWII. The shrine's site dates to 202 C.E., but because it used to be torn down and rebuilt every 20 years as a purification ritual, the oldest sections now date back to 1810. Sumiyoshi-Taisha is considered pure Japanese architecture, free of Chinese or Korean influence. To the casual observer, it merely looks more angular than most shrines; to the expert, the important details include door placement and the surrounding fence. Well worth the visit.
