around the seaward face of the tower, which served as a blockhouse. Both batteries still survive, although they are either in a dilapidated state or extensively altered. Fougasses were dug in the ground near some of the towers in the 1740s. Today, fougasses still exist near Madliena Tower and Saint Mark's Tower. In the 1760s, entrenchments were also built close to some towers, but many of these were demolished in the early 20th century. A small mortar battery was built close to Delimara Tower in 1793. The De Redin towers did not play a role during the French capture of Malta in 1798, since by this time they were obsolete. However, St. Julian's Tower was involved in the subsequent Maltese uprising, when it was captured by Maltese insurgents. British period 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. Most of the other towers were decommissioned in the 19th century. The only exception was Madliena Tower, which was modified to have a role similar to the Martello towers. A battery was built nearby in 1908, and it remained in use until World War II.

Conservation and restoration By the end of the 20th century, there were nine surviving De Redin towers. Most of these were intact but rather dilapidated. Triq il-Wiesgħa Tower and Ħamrija Tower were in a very bad state, and were in danger of collapsing. The first restoration work was carried out by Din l-Art Ħelwa on Għallis Tower and Saint Mark's Tower between 1995 and 1997. Since 2008, Fondazzjoni Wirt Artna has restored Triq il-Wiesgħa Tower and Madliena Tower. Ħamrija Tower was also restored by Heritage Malta, and it now forms part of the Ħaġar Qim and Mnajdra Archaeological Park. The last remaining towers to be restored were Aħrax Tower, restored by Din I-Art Ħelwa in 2021, and Wardija Tower, restored by the Restoration Directorate in 2022. Today, Għallis Tower and Saint Mark's Tower are open by appointment, and Saint Julian's Tower is open as a restaurant.
