Introduction
Concrete domes, sometimes referred to as “the umbrella of the future,” have their origins in ancient Roman architecture. Initially utilized for grand structures like the Pantheon, these domes represent a significant advancement in architectural design and engineering. Their ability to span large spaces with minimal support has granted them a historic importance that resonates through the ages.
Timeline
