These early structures featured gaps in stacked stone that provided interior illumination, a clever solution for natural lighting in buildings.

In the modernist period, advancements in steel and glass construction made clerestory windows even more accessible, highlighting the post-and-beam construction of the day and establishing deeper connections to nature.

Today, you can find clerestory windows across many design styles in both residential and commercial buildings, a testament to their enduring popularity and versatility.
