Residents of the 40-plus houses in the square formed at Weldon Avenue and Fairmount between 11th and 12th streets in Phoenix are hiding a secret. The subdivision, which opened in 1928, includes a three-acre private park in the square of land concealed by properties. The park originally housed a golf course, artisan well, tennis court, fireplaces, and a swimming pool made from native stone. The pool may be all that's left of the original plan, but the fact that most of Phoenix remains unaware of this hidden gem proves that the garden is still a safe, quiet, and secret place to play.
