Where is the "Home for the Aged"?

It was during this second phase of the World Crusade that the American National Assembly purchased the land for its first Temple dependency. The Guardian had advised that Assembly that he did not consider a library—the first proposal—sufficiently demonstrative of the purpose and significance of the institution of the Mashriqu’l-Adhkár in Bahá’í society and it was therefore decided to build a Home for the Aged. One of his last letters was to urge that Assembly to commence work on the Home, as it would impress on the public that one of the chief functions of our Faith is to serve humanity, regardless of creed, race or denomination, and be sure to attract attention and publicity.
