さざえ堂は二重らせん構造の斜路を持つ特異な建物として知られる。福島県会津若松市の白虎隊も墓所のある飯盛山ン中腹に建つ。通称は「会津さざえ堂」もしくは単に「さざえ堂」で、正式名称は「円通三匝堂」（えんつうさんそうどう）という（重要文化財指定名称は「旧正宗寺三匝堂」）。
平面六角形の特異な建物である。概ね三層構造と言えるが、内部には二重らせん構造の斜路が続き、右回りに上る斜路と左回りに下りる斜路が別々に存在する。入口から斜路を最上階まで上り、他社とすれ違うことなく、別の斜路を降りて出口から出ることができる。
かつてこの地にあった正宗寺の仏堂として、江戸時代後期の寛政８年（１７９６年）に当時の住職であった郁堂（いくどう）が建立したものである。当時は阿弥陀如来を本尊とし、斜路には三十三観音像が安置されていたという。神仏混交の信仰形態を持っていた正宗寺は、明治初期
の廃仏毀釈で廃寺となり、以後、さざえ堂は個人の所有となっている。また、堂内にあった三十三観音像は他所へ移され、代わりに「皇朝二十四孝」の額が取り付けられている。平面は一辺3.4ｍの六角形で、堂内中央部に６本の通し柱を立てる。側柱（建物外周に建つ柱）も６本の通し柱で、中央柱との間には繋梁を渡す。屋根は銅板葺きとし、正面入口には唐破風造の向拝を設ける。最上部の天井は折上げ鏡天井とする。
同名の堂は他所にもあるが、旧正宗寺三匝堂のような特異な内部構造をもった堂はほかに知られず、稀有な例として平成７年（１９９５年）６月２７日付けで国の重要文化財に指定された。（Wikipediaより抜粋）

Sazaedo is known as a unique building with a double helix slope. Byakkotai in Aizuwakamatsu City, Fukushima Prefecture, is also built on the hillside of Mt. Iimori, where the graveyard is located. The common name is “Aizu Sazaedo” or simply “Sazaedo”, and the official name is “Entsu Sansodo” (important cultural property designated name is “Former Shosoji Sankodo”).
It is a peculiar building with a flat hexagon. Although it can be said that it has a three-layer structure, there are double-helical slopes inside, and there are separate slopes that go up clockwise and those that go down counterclockwise. You can go up the slope from the entrance to the top floor, get off another slope and exit from the exit without passing by other companies.
The Buddhist temple of Shosou-ji, which used to be in this area, was built by Ikudo, who was the chief priest at that time, in the 8th year of Kansei (1796) in the latter half of the Edo period. At that time, Amida Nyorai was the principal image, and it is said that 33 Kannon statues were enshrined on the slope. Sazaedo, which had a form of worship of mixed gods and Buddha, was abandoned due to the abolition of Buddha in the Meiji era, and since then, Sazaedo has been owned by an individual. In addition, the 33 Kannon statues in the hall have been moved to another place, and the forehead of “Twenty-four Takashi of the Empire” is attached instead. The plane is a hexagon with a side of 3.4 m, and six through pillars are erected in the center of the hall. The side pillars (pillars built on the outer circumference of the building) are also six through pillars, and a connecting beam is passed between them and the central pillar. The roof will be copper-roofed, and the front entrance will be equipped with a gabled gable. The ceiling at the top will be a folded mirror ceiling.
There are other temples with the same name, but no other temple has a unique internal structure like the former Sazaedo Temple, and as a rare example, it was dated June 27, 1995. It was designated as a national important cultural property. (Excerpt from Wikipedia)
