In October 2017, an educational archaeological excavation was conducted at Khirbat Buleiʻis (Permit No. A-8115; map ref. 179617–797/629562–691; Fig. 1), inside the IDF Ariel Sharon Training Campus, with the aim of preserving and developing the ancient site. The excavation, undertaken on behalf of the Israel Antiquities Authority and financed by the Israel Nature and Parks Authority, was directed by H. Mamlya (field photography), with the assistance of Y. Alamor (administration), E. Aladjem (aerial photography and mapping), O. Finkelstein (architectural conservation), Y. Regev (education and training), as well as Y. Abadi-Reiss and Y. Haimi (professional guidance) and members of the Bnei HaMoshavim youth movement also participated in the excavation.
The excavation (50 sq m; Fig. 2), in the Nahal Sekher streambed, unearthed three walls: two poorly preserved walls (W50, W51), which ran across the streambed along a northwest–southeast axis; and a wall (W52) that delineated a circular installation. The walls were built of local hard limestone with flint concentrations, and were founded on the loess soil. Wall 50 (width 0.2 m, height 0.3 m; Fig. 3) survived only one course high; it was built of a single row of stones of various sizes. Judging by the number of collapsed stones surrounding it (L102), the wall obviously had several more courses. Walls 51 and 52 (Fig. 4) were unearthed farther down the streambed. Wall 52, which had a circular course, was built of stones of uniform size with a dressed outer face. Wall 51 (width 0.3 m, height 0.4 m) was built over W52. The wall, built of two courses of stones of various sized, was only partially preserved. Walls 50 and 51 probably functioned as agricultural terraces, as they retain a leveled plot of farming land extending upstream, similar to those identified in previous excavations. Wall 52 delineated a rounded installation.
At the top of the northwest slope of the streambed, northwest of the walls (not on plan), were remains of a quarry: hewn steps, quarrying marks and scattered debris. Due to their geographic proximity to the stone-built terraces and since the building stone are of the same rock as the bedrock, it seems that this quarry was the source of the building material for the walls.
Although no datable finds were found, the installation delimited by W52 predates Agricultural Terrace 51, and probably went out of use with the construction of W51.
It seems that the two agricultural terraces walls, which served to retain a terrace of farming land, and the rounded installation that predated them were part of the agricultural hinterland of the settlement excavated at Khirbat Buleiʻis. They were therefore probably used over a single timespan, possibly in the late Byzantine and beginning of the Early Islamic periods (sixth–eighth centuries CE).
