Phalanstère
（重定向自Phalanstery）
A phalanstère (or Phalanstery) was a type of building designed for a utopian community and developed in the early 19th century by Charles Fourier. Fourier named these self-contained communities, ideally consisting of 500–2000 people working together for mutual benefit, after the phalanx, the basic military unit in ancient Greece.
