The physical structure of the park was designed by the house architect Erich Mendelsohn as an integral part of the house. The vegetation was planned by the park architect Shlomo Weinberg-Oren from Kibbutz Yagur, who planned several parks, including the Yad Hanadiv Park in Zichron Yaakov.
Dr. Chaim Weizmann asked to be buried on the estate next to his home. On his death, the headstone was designed with the simple inscription "Chaim Weizmann". In his will, Weizmann asked for a simple grave: ".. I was always a simple Jew from Motal, and that's how I want to remain after my death…"
Dr. Vera Weizmann asked to replace the original headstone, a marble stone bearing Weizmann's name and dates of birth and death. Vera wished to be buried next to her husband. She wanted the headstone to mention their private grief, the death of their younger son Michael, who was killed in World War II. The new headstone was designed according to the Tomb of the Missing Soldier in England in 1962. It was designed by sculptor Moshe Ziffer. Engraved in the center of the stone is the emblem of the Weizmann Institute of Science, designed by Erich Mendelsohn at the request of Dr. Weizmann as the logo of the Sieff Institute. The emblem is engraved between the names of the Weizmanns.
In 1950, Henry Ford II presented to Dr. Chaim Weizmann a Ford Lincoln Cosmopolitan, one of a series of 18 cars of this type, that were made to a special specification designed for the US President. The car became the official vehicle of the State President, and after Weizmann's death in 1952, it was put on display at the Weizmann House. Over time, due to exposure to the elements, the vehicle's glory faded. Delek Motors, the importer and distributor of the Ford Lincoln in Israel, undertook, together with the Ford Company in the United States, the task of restoring and preserving the car. The work took 13 months, after which the vehicle was returned to a special display structure designed by the architect Hillel Shocken.
The Memorial Plaza
The Plaza was built in the early 1960s as a memorial to Chaim Weizmann, and in 1972, a Memorial to the Holocaust by Dani Karavan was placed there. The monument is made of chalkstone and bears a Scroll of the Law (Sefer Torah). The stone itself, weighing 22 tons and 2 meters high, was quarried in Israel. The Sefer Torah was cast in bronze in Italy. The Scroll is 1 meter high and weighs 9 tons.
Engraved on the stone is an extract from Dr. Weizmann's eulogy for the Holocaust victims, in a speech given at the 1946 Zionist Congress. This was the first Congress after the War and the Holocaust – and the last for Weizmann as President of the Zionist Federation.
