Hisar is a Turkish word that means fortress or fortification wall. In common use, it also refers to rocky landforms that resemble fortifications.
Hisar Studies is a series of gabion constructions using textiles as a structural and representational skin for rubble and gravel piles. The compressive load of the fragmented ground is re-organized vertically by the running bond, ashlar masonry pattern of the crocheted skin in tension.
Crocheted fabric, like a masonry wall, is built through a process of stacking one stitch-unit atop another (as opposed to most other textile constructions, which require a warp and a weft, a construction process more similar to framing systems in architecture).
Gabion masonry systems were first used in Europe as portable fortifications by besieging armies, who filled the baskets they brought with them with gravel and rubble from the battle-ground.
