Little information is known about Falzon, and his date of birth is not recorded. The councilors were impressed at Falzon's expertise in military engineering, especially since he was familiar with the Italian system of
bastion fortifications which had revolutionized European military architecture. Soon afterwards he was commissioned to design improvements to the
city walls of Nuremberg and the
Lichtenau Fortress. Work on the (also called
Fazuni-Bastion after the architect) in the vicinity of the
Nuremberg Castle began by July 1538 and were completed in late 1544 and they are possibly the earliest example of bastioned fortifications in the Italian style ever to be built north of the Alps. although there is no direct evidence supporting this attribution. Some German historians refer to Falzon as a
Renaissance man due to his interest in multiple areas. He seems to have been capable of designing and making tools and instruments, and he is also credited with introducing
cornerstone medals (a medal commemorating the construction of a new building) into Germany during his work on the Nuremberg fortifications. Falzon's attempts to extend his activities into areas other than military engineering resulted in disputes with the city's powerful guilds. He is also known to have had a number of disputes or clashes with the authorities or his workers, and he was described as being arrogant. ==Legacy==
