monolith
A "monolith" refers to a large, single block of stone or rock, often used in architecture or sculpture. These structures can be natural formations, like Stonehenge, or man-made, such as Obelisks. Monoliths are typically characterized by their impressive size and solidity, making them significant in various cultures and historical contexts.
In a broader sense, the term "monolith" can also describe a large, unified system or organization that operates as a single entity. In technology, for example, a monolithic application is a software program built as a single, indivisible unit, which can make it easier to develop but harder to scale or modify.
