Castel National Park, Crusader castle ruins in Mevaseret Zion, Israel.

Castel National Park is a fortified site in the Judean Mountains near Mevaseret Zion containing stone structures and defensive walls. The ruins sit on a high point overlooking the main highway connecting Tel Aviv and Jerusalem.

The site witnessed multiple battles during the 1948 War, with a decisive battle following the death of commander Abd al-Qadir al-Husayni. Control of this strategic location changed hands several times during the conflict.

The hilltop carries bronze plaques that recount the fighting of April 1948, and a 1980 monument by Yitzhak Yamin honours the battle's fallen. A separate memorial recalls the convoys that tried to break the blockade of Jerusalem. The Jewish village of Maoz Zion was founded at the foot of the hill in 1951.

The park is located about 8 kilometers west of Jerusalem along Highway 1 and provides visitors with detailed maps and guided tours. Walking routes lead through the archaeological remains, allowing you to explore the site at your own pace.

Romans built a fortress called Castellum at this location, which was later replaced by Crusaders with their own Castellum Belveer. Although these structures are no longer visible on the surface, archaeological finds confirm their former presence.
