This Givatayim nest was established in 1929, one of the first, and is considered until today among the major ones in Israel. The building always looked to me like a prison, if you go down the stairs to the little garden you will see the back facade of the building and understand why..
The garden is named after Yaniv Viser, a graduate of the youth movement, who died in the Beit Lid terror attack in 1995. In the garden there is a playground for children, outdoor gym, and benches to sit and rest.
