The Domes of Casa Grande, Industrial structures in Pinal County, United States.
The structures consist of multiple interconnected concrete domes, including one resembling a flying saucer and three spherical formations joined in sequence.
Built in 1982 for InnerConn Technology Inc, these structures were designed for computer manufacturing but remained incomplete due to project abandonment.
The domes gained attention from photographers and urban explorers until their demolition in January 2023, following years of deterioration.
Prior to demolition, visitors could reach the site by taking Interstate 8 Thornton exit and traveling south for one mile on the east side.
The combination of concrete and polyurethane foam construction materials proved unsuitable for the desert environment, leading to structural failure.
