What is an example of post-and-lintel construction?

Post-and-lintel construction is an architectural system that uses vertical elements (posts) to support horizontal elements (lintels). This type of construction is characterized by its straightforward composition, where beams or slabs are laid across two or more vertical supports.

Stonehenge is an example of post-and-lintel construction because it consists of massive vertical stones (the posts) that hold up horizontal stones (the lintels) that rest on top of them. This arrangement allows for open, spacious structures and has been utilized in various architectural forms throughout history. The iconic circular layout of the stones at Stonehenge showcases the effectiveness of this technique in both structural stability and artistic expression, making it a notable example within ancient architecture.

In contrast, Egyptian pyramids involve a different construction method primarily focused on large, interlocking stone blocks, creating a solid mass rather than an open framework. Gothic cathedrals utilize ribbed vaults and flying buttresses that extend beyond the simple post-and-lintel system, showcasing more complex architectural advancements. The Colosseum integrates an arch-based construction, which supports its massive scale through a series of arched vaults rather than the straightforward post-and-lintel structure.
