The Senglea spur is part of defensive walls and other fortification which surround the city of Senglea. The Spur is in the seaward bastion of Senglea, facing Valletta. It contains a reconstructed echaugette (the original had been dismantled in World War II), and its top part is now a public garden known as Gardjola Garden. The first fortifications were built circa 1552, but through the years modifications and demolishing took place. Today, what is left of the fortifications are part of the UNESCO World Heritage Sites. In the recent years the whole spur was restored and served as a major role in the Valletta 18 opening night, since projections were put on for thousands of audiences to enjoy from Valletta Grand Harbour.
