No other significant structure of antiquity has survived as well preserved nor with the roof intact.

Remembering Larry Byrne, 1942-2024

On Tuesday, April 23, 2024, we laid to rest our friend and colleague, James Laurence Byrne, in the Sutton Cemetery near Rexburg, Idaho. Larry was a family man, church and community leader, farmer, former Air Force Captain, and a pioneer in the Monolithic Dome industry. For three decades, Larry served as chief designer at Monolithic, where he designed everything from houses to giant storages, developed standardized design elements still used across the dome industry, and consulted with engineers and architects as they worked to become familiar with dome design.
