From the World Heritage inscription:
Battir is a major Palestinian cultural landscape, the adaptation of a deep valley system for agricultural purposes as a result of a good supply of water. The complex irrigation system of this water supply has led to the creation of dry walls terraces which may have been exploited since antiquity. The agricultural terraces, exploiting this irrigation system, were the basis for a strong presence of agriculture through the cultivation of olives and vegetables. The area still today has the same use.
The water distribution system used by the families of Battir is a testament to an ancient egalitarian distribution system that delivers water to the terraced agricultural land based on a simple mathematical calculation and a clear time-managed rotation scheme.
The village of Battir is not far from Jerusalem and is right on the Israel/Palestine border. In fact, there are Israeli train tracks which go right past the terraces at the bottom of the hill.
I could not find any organized tours to Battir, which was a shame. Nearby Bethlehem gets most of the attention in the region. That being said, it wasn’t that hard to get to Battir from Bethlehem. I had my tour guide in Bethlehem call a taxi for me which took me to there. It took about 15 minutes and cost about $10.
Battir is a fairly new world heritage site and as such the tourism infrastructure isn’t well developed. There are a few souvenir shops and cafes, but that’s about it.
The terraces are easily accessible if you are on the main street of the village. Expect to spend 30-60 minutes walking around the area. This site is probably going to be of interest to world heritage enthusiasts more than anyone else. Nonetheless, I think anyone visiting Jerusalem would be well off to come and visit a small Palestinian village, which Battir fits perfectly.
