What does the term "post and lintel" describe in architecture?

The term "post and lintel" refers to a fundamental architectural system where vertical supports, known as posts, bear the weight of a horizontal beam, or lintel, placed across them. This construction technique forms the basic framework for many structures, including ancient temples, houses, and modern buildings. It allows for the creation of doorways and windows by relying on the rigidity and strength of the horizontal beam while distributing weight effectively to the vertical supports.

This method of construction is one of the oldest and simplest in architecture, dating back to ancient times and is pivotal in understanding how larger spaces can be enclosed while still maintaining structural integrity. It contrasts with other architectural styles such as arches and domes, which employ different principles and distribute loads in alternative ways. The use of post and lintel was crucial in the development of monumental architecture throughout history, illustrating how basic geometric principles can be applied to create functional and aesthetically pleasing spaces.
