Antonio Ferramolino was a 16th-century Italian architect and military engineer. He is also known as Sferrandino da Bergamo, and is called Hernan Molin in Spanish sources. He is mostly known for his work in Sicily, but he also designed fortifications in Croatia and Malta.
Ferramolino was born in Bergamo, which was then part of the Republic of Venice. He began his career as a soldier, but little is known about his early works. In 1529 he oversaw the construction of artillery at the Venetian Arsenal.
In 1532, he fought against the Ottomans in Hungary. Ferramolino was also present at the conquest of Tunis in 1535. In 1536, Emperor Charles V sent him to review the fortifications of Messina and the rest of Sicily. Over the next couple of years, he designed several fortifications around Sicily, including at Messina, Palermo and Catania.
In 1540, he was sent to Malta, which was ruled by the Order of Saint John. He designed the cavalier and ditch of Fort St. Angelo, and designed two bastions of the fortifications of Mdina. He also proposed the construction of a fort on the Sciberras Peninsula.
