Kenuna Tower
Ta' Kenuna Tower is a semaphore tower on the cliffs near Nadur on the island of Gozo, Malta. It was built by the British in 1848, as one of three semaphore towers in Malta. The tower was restored in 2005, and it now houses as a beacon to warn ships of their proximity to land, as well as a number of communication antennas.

If you look carefully you would see the year when the tower was build (1848)
Also next to the tower there is a botanic garden, but it was poorly maintained at the the time. But anyway it was still worth to view the place.
Thanks for all the support!
