Hussamssa, Heritage site, museum and park in Holon, Israel.

Hussamssa is a park, museum, and heritage site in Holon, Israel, combining outdoor green spaces with indoor exhibition areas focused on local history. The site brings together these functions in a single location within the city.

The land was bought in 1934 from local Arabs by Yaakov Mirnburg and Shimon Yavetz, owners of Agrobank, who built the two-storey fortress-like well house with its tower. From its construction until 1948 it served as a Haganah training site for weapons, signalling, first aid and hand-to-hand combat, and the well and grove hid arms. In the 1948 war it was an observation and Morse, heliograph and flag signalling post on the Tel Aviv–Jerusalem–Negev route. The museum opened in 2009 after renovation.

The name Hussamssa probably comes from the Arabic name of a soil layer in the coastal plain. The museum, called Yad LaHaganah, presents the Haganah's activity in Holon during the 1948 war, and the garden holds a Davidka mortar tested here, a mortar, an armoured car and marked slik hiding places. Playwright Haim Nagid set his 1989 play "Picnic in Hussamssa" here.

The site is easy to reach within Holon and can be explored on foot. Allow enough time to visit both the indoor exhibition areas and the outdoor spaces without rushing.

What sets this place apart is that visitors can encounter history while walking outdoors, not only inside exhibition rooms. Memory and everyday life are brought together in a way that is rarely found in a single site.
