The Delle Grazie (Batterija Tal-Grazzja) Sound Locator is built within the old Del Grazie coastal defence battery. The layout of the position has been modified to conform to the battery.
The sound locator pen is located in the North corner of the battery and is similar in design to Ghajn Tuffieha Sound Locator position. The garage for the sound locator survives intact. As with other locations, loop holes have been cut in the wall of the locator pen with concrete fire steps.
The searchlight is situated below the locator pen, with the platform being within one of the gun emplacements. A section of track can be seen running from the garage out to the operational position.
