The Nabi Yusha fort, renamed Metzudat Koach (Hebrew: מצודת כ"ח), is a police fort built by the British Mandate administration during the 1936–39 Arab revolt in Palestine and currently used by the Israel Border Police. The site around the fort contains a stone monument and a small museum, together constituting the Metzudat Koach Memorial, which commemorates 28 Israeli soldiers who died during the 1948 conquest of the strategically important fort. The fort and observation point is located in the Upper Galilee, close to an abandoned Shia shrine of Nabi Yusha ("Prophet Joshua"). The Hebrew word "ko'ach" (כח) has a double meaning: as a common noun it means "strength", while its numerical value according to gematria is 28, the number of the fallen soldiers.
The Metzudat Koach memorial is currently part of the Israel National Trail.
The building is a Tegart fort commissioned by the British and constructed by Solel Boneh, the fort was a key observation point on the Naftali heights, overlooking the Hula Valley, and used to monitor the Palestine/Lebanon border.
