Centennial Memorial Tower

Monument in Sapporo

Construction of this modernist tower, designed by architect Iguchi Ken, started in 1968 to mark Sapporo's centennial (it was completed in 1970). The footprint is a hexagon, to evoke a six-sided snowflake; a cross-section reveals the kanji for 'north' (北; kita). It's in Nopporo Shinrin-kōen, a short walk behind the Hokkaidō Museum.
