Nahal Zanoah is a stream that runs north and drains into Nahal Sorek.
The ruins (Khirbe Zanu') south of the moshav are probably the ancient village of Zanoah mentioned in Egyptian letters, later part of the tribe of Judah (Joshua 15:34), and in the "Second Temple Period ... reinhabited", as also written in the Bible (Nehemiah 3:13).
The Beit Shemesh Yeshiva is located in Zanoah. Most of the students are from Ramat Beit Shemesh Alef. Aside from Talmud study, the curriculum includes English language and mathematics, and unlike many such institutions in Israel today, students study for the Bagrut matriculation exams. In addition to this, Zanoah is the home of Yeshivat Yesodei HaTorah, for International Engish-Speaking Students where boys can study within a gap year programme there.
