Buttress (Civ6)

Buttress is a Medieval Era technology in Civilization VI: Gathering Storm. It can be hurried by building a Classical Era or later wonder.
== Strategy ==
Mathematical developments lead to the invention of this important architectural element, which allows civilizations to build very interesting and large structures capable of supporting incredible stress. The element quickly finds use in civil construction, enabling the next stage of large-scale infrastructure. We're talking about the Dam, a district that is both the most reliable protection against river floods and a useful source of midgame . This tech also unlocks the Hagia Sophia, an important wonder for any religious player.
Buttress is an indispensable tech for seafaring civilizations since it leads to Cartography and Mass Production, both of which represent the next level of exploration and naval military tech. These, in turn, lead to the later Industrialization, which unlocks a sea of new opportunities for players. However, all of this is quite forward-thinking (i.e., two eras in the future). More immediately, the Dam is a nice new addition, but not that urgent to build unless your cities close to Rivers have hit their ceiling. Unless you're an exploration aficionado, you should go for other Medieval techs first, such as Apprenticeship.
