on 29 February 2004 in a ceremony attended by army chiefs, the Israeli Defense Minister Shaul Mofaz, and members of the Jerusalem Municipality at the National Military and Police cemetery. The garden also contains memorials to those lost aboard the submarine INS Dakar and the 23 Who Went Down at Sea. An annual memorial service for the Missing Soldiers of Israel takes place in the garden's main plaza on Seventh of Adar day. The garden includes "empty graves" and stone monuments to the memory of missing soldiers. At the entrance to the garden, there is a small plaza where memorial ceremonies to the missing are held. On the north side of the plaza there is a memorial to the missing sailors of the INS Dakar submarine, which sank in the Mediterranean sea. On the north side of the plaza is a memorial wall bearing the names of all missing soldiers and fighters from 1914 until today. On the top of the wall there is a waterfall. National Memorial Hall For Israel's Fallen A national memorial hall was built at the entrance to the National Military and Police cemetery to honour the memory of the 22,684 soldiers and security personnel who have fallen defending the land of Israel since 1860. It is designed in the shape of a torch rising some 18 meters and an eternal flame burns there all year long. A candle for each soldier is lit twice a year — once on the anniversary of the soldier's death, and on Memorial Day. The cost of the project was NIS40 million. Gardens Above the Herzl Museum and the main plaza is the Nations Garden, where trees have been planted by visiting presidents and heads of state. There are two small observation decks looking out over Jerusalem. A menorah sculpture stands opposite the main plaza entrance. Situated between the Herzl Museum and the Stella and Alexander Margulies Education Center, the Stephen Norman Garden is named for Herzl's grandson, Stephen Norman. He was the only member of Herzl's family to visit Palestine or to be a Zionist. It is a place for groups and students to gather to hear about Mount Herzl. On one wall of the garden, a quote from Norman, in 1945, is inscribed: "You will be amazed at the Jewish youth in Palestine...they have the look of freedom."
