Tenaglia (Italian for "pincers" or "tongs") primarily refers to two distinct concepts:
-
Fortification: In historical military architecture, a tenaglia is a type of outwork or defensive structure typically found in fortifications from the 17th and 18th centuries, particularly associated with the Vauban system.
- Design and Purpose: It consists of a V-shaped or pincer-shaped earthwork or masonry structure placed directly in front of the curtain wall (the main wall connecting two bastions). Its primary purpose was to cover the curtain wall from direct enemy fire, provide additional lines of defense, and create a re-entrant angle (an angle pointing inwards towards the fortress) that could deliver flanking fire against attackers approaching the main defenses. Unlike a ravelin, which stands further out, a tenaglia is typically closer to or integral with the main enceinte.
- Types: Tenaglias could be simple (a single V-shape) or double (two V-shapes creating a zig-zag). They sometimes incorporated small flanks or orillons to further enhance their defensive capabilities.
- Historical Context: Tenaglias were a feature of sophisticated trace italienne (Italian trace) fortifications, designed to maximize defensive fire and minimize vulnerable straight lines. They were often part of complex outer works that also included ravelins, lunettes, and hornworks.

Surname: Tenaglia is an Italian surname.
- Etymology: The surname likely derives from the Italian word "tenaglia," meaning "pincers" or "tongs." It may have originated as a metonymic occupational surname for someone who made or used pincers (a smith or craftsman), or it could have been a topographical surname for someone who lived near a feature resembling pincers, such as a V-shaped valley or a fortification like the one described above.
- Distribution: The surname is found throughout Italy, with a notable concentration in certain regions. As with many Italian surnames, various individuals bearing the name may be found in different fields, though none are universally recognized as singular historical figures on the scale of, for example, Leonardo da Vinci.
