浅草のシンボルと言えば五重塔。
5重の塔とは仏舎利(釈迦の遺骨)を奉安するための仏塔です
942年に建てられてから、火事で何度も崩壊し、1973年に鉄筋コンクリートに作り替えられました。
太く大きい柱を天井からぶら下げ、重塔を構成する各部材は、きっちりと組合さずにわざと緩みを持たせています。この各部材の緩みと、心柱の振り子の作用によって、
縦揺れ、横揺れの地震にも逆らわず、吸収して崩壊を防いでいるそうです。
夜のライトアップはお勧めです
The five-story pagoda is a stupa to enshrine the stupa (the remains of Buddha).
Since it was built in 942, it has been destroyed by fire.
It collapsed several times due to fire and was rebuilt with reinforced concrete in 1973.
Large, thick pillars hang from the ceiling, and each component of the stacked towers is intentionally loose without being tightly joined.
The looseness of each member and the pendulum action of the central pillar are the main elements of the pagoda,
The tower does not resist vertical or horizontal shaking of earthquakes, but absorbs them to prevent collapse.
Illuminated five-story Pagota is very beautiful at night
