Memorial Mosaic for the Herzliya Hebrew Gymnasium, Memorial mosaic at Shalom Meir Tower, Tel Aviv, Israel

The Memorial Mosaic for the Herzliya Hebrew Gymnasium is a wall mosaic by Nahum Gutman, unveiled in March 1967 at the entrance of Shalom Meir Tower, on the site of the school's original building. Covering about one hundred square metres, it is made of more than a million stones in some eight hundred shades, set by six Italian mosaicists led by Renato Signorini of Ravenna. Four colour-coded panels trace Tel Aviv's development: green for old Jaffa and its orchards, yellow for Ahuzat Bayit on the sand dunes, red for Herzl Street and its first street lamp, and blue for the 1930s and 1940s port era.

The Herzliya Hebrew Gymnasium, one of the first Hebrew high schools, stood on this site until it moved to Jabotinsky Street in 1958; the building was then demolished for Shalom Meir Tower. Nahum Gutman, a graduate of the school, made the mosaic in 1966 in Ravenna and gave it to the city; it was installed at the tower in early 1967 and inaugurated that March.

The mosaic depicts four periods in Tel Aviv's development, each with a different background colour: green for old Jaffa and its orchards, yellow for Ahuzat Bayit with Meir Dizengoff and Haim Hisin on a donkey, red for Herzl Street and the city's first street lamp, and blue for the 1930s and 1940s and the opening of Tel Aviv port.

The artwork can be seen at the base of Shalom Meir Tower at the intersection of Herzl and Ahad Ha'am streets. It is freely accessible and can be viewed from outside, making it easy to visit while walking around the area.

The mosaic was assembled in Ravenna by six Italian craftsmen led by mosaicist Renato Signorini, using more than a million stones in about eight hundred shades; it was installed in Shalom Meir Tower in early 1967 and inaugurated that March. Gutman, a graduate of the Herzliya Gymnasium, gave it to the city's residents as a memorial to Little Tel Aviv and the school.
