Falka Gap Sound Locator lies on the escarpment at the Eastern end of the Dwejra Lines. The basic design is similar to Mgarr and Ghajn Tuffieha, but because of the limited space it has been rather compressed.
The locator pen with garage for the sound locator, is situated on the edge of the escarpment. The searchlight complex is situated to the rear of off set to the West. Both are in reasonable condition.
