The inner gate (Hōzōmon 宝蔵門) of the Sensō-ji 金龍山 浅草寺
This gate was rebuilt in 1964 with concrete to replace the one destroyed during WW2. Because of its use of flame-resistant materials for construction, the treasures of the temple are kept in its upper floor. This was the reason for renaming it from Niōmon 仁王門 to Hozomon or Treasure-House Gate.
