In March 1658, he contributed 6428 scudi[1] for the construction of 13 new watchtowers to strengthen the existing coastal defence system, which consisted mainly of the Wignacourt and Lascaris towers.

[8] The upper floor of Għajn Ħadid Tower collapsed on 12 October 1856 during an earthquake, but the ruins of its base have survived to this day.

Ħamrija Tower was also restored by Heritage Malta, and it now forms part of the Ħaġar Qim and Mnajdra Archaeological Park.

One of the earliest examples is the Torre dello Standardo, a tower located near Mdina's Main Gate, forming part of the city's fortifications.

It was built in 1725 by the architect Charles François de Mondion, on the site of the medieval Torre Mastra (which also had the same function), as part of a project to restore the city after the 1693 Sicily earthquake.

Its design is similar to the De Redin towers, but it is of finer construction, with more importance being given to decorative elements such as escutcheons.

[19] The emblem of the Armed Forces of Malta (AFM) consists of a gold De Redin tower on a red background.

[20] A symbol of a De Redin tower is also featured on pennant of the Commander of the AFM,[21] on the emblem of the Air Wing, on the National Colours, and on various badges of rank.

[22] The coat of arms of the Malta Stock Exchange features two gold De Redin towers on either side of the shield, representing security and surveillance.

De Redin towers also feature on the flag and coat of arms of Pembroke, a town on the northern coast of Malta.

The coat of arms consists of two crossed swords in the centre, with the thirteen De Redin towers around the border, all in gold on a red background.

The sword and towers represent Pembroke's connection with the military, since the town developed out of a British Army barracks that was converted into housing estates.
