The Cottonera Lines are a massive line of fortifications surrounding the Three Cities of Vittoriosa, Senglea, and Cospicua, in Malta. They are entirely built on four of the Bormla (Cospicua) hills. Grand Master Cottoner is still inked to Bormla with his surname's coat-of-arms now depicted in the emblem of the Bormla Local Council. They were designed by Italian engineer Antonio Maurizio Valperga in the 17th Century, and named after Grand Master Nicolau Cotoner.
