Maghtab Sound Mirror

Sound mirrors are large acoustic deflectors, used for early warning of approaching aircraft.
Unlike the earlier Semi-Spherical sound mirrors of the South Coast of England, this mirror is in the form of a stone built parabolic wall, 225 feet in length.

It’s known locally as Il-Widna, Maltese for “the ear”.

A series of these walls was planned for the defence of Malta, but owing to the early development of radar this was the only one to be completed. It is orientated towards Sicily. Trials showed that it was effective at a range of over 25 miles, although operators needed to be highly trained before these levels of sensitivity could be achieved.

The first photograph shows the face of the wall, upon which can still be seen the remnants of its original “field boundary” camouflage. Although highly visible from ground level it is remarkably effective from height.

The second photograph shows the butressed rear and the control room at the centre back, note the remains of the camouflage, red in this area.

Maghtab (properly written with the h crossed in the manner of a “t”) is approximately four miles NE of Mosta, about a mile from the coast.

The Site is surrounded by high-security fencing, in order to protect not only the sound mirror, but also the sattelite installation of MaltaCom, the island’s telecom company.

Defence Structures and sites of all types both above and below ground can be very dangerous. Serious injury or even death can arise from unauthorised entry into such sites and structures. Join a responsible club, group or society who can arrange official visits. The Pillbox Study Group accepts no responsibility for any damages or injuries caused by ignoring this advice. The PSG does not encourage members to undertake the ad hoc clearance of vegetation from pillboxes, as it can expose them to physical damage and inappropriate use, it may also contravene a variety of statutory regulations including, listed buildings and SSSI designations. Vegetation clearance should only ever be undertaken as part of a formal arrangement, having sought and obtained permission from the land owner and other necessary authorities. Damaging a listed or scheduled monument can be considered as a Heritage Crime.
