The tower was restored in 2005, and now houses a beacon to warn ships of their proximity to land, as well as a number of communication antennas.

Initially, it was planned that semaphore stations would be established on the bell towers and domes of the island's churches, but the religious authorities rejected the proposal.

Due to this, in 1848 new semaphore towers were constructed at Nadur on Gozo, and Għargħur and Għaxaq on the main island of Malta.

The semaphore system became obsolete with the introduction of the electrical telegraph, and Ta' Kenuna Tower closed in 1883.

[2] The modern additions are mounted on the surface of the tower, and care was taken to preserve the historic fabric of the original structure.
