The Domes In Casa Grande Are Gone – The iconic concrete domes located near Casa Grande, Arizona, have finally been demolished after years of being a local curiosity and a hub for photographers, artists and vandals.

The structures, which were built in 1982 as the headquarters for InterConn Technology, a former electronics manufacturer, have been in a state of disrepair for decades and were no longer considered safe by local authorities.

The domes, which were constructed using a unique blend of polyurethane foam, concrete and reinforced with metal fibers and rebar, were designed as an unconventional and futuristic approach to building construction. They quickly became a popular tourist attraction, with travel websites like Atlas Obscura and shows like the “Ghost Adventures” featuring the structures.

However, over the years, the domes fell into a state of disrepair and were condemned as unsafe by Pinal County. The property owners, Dan and Karon Peer, had been in an ongoing legal battle with the county over the safety of the domes for several years. Pinal County officials requested that the property owners have an engineer assess the domes’ safety or block them from public access, but when the owners failed to do so, the county was forced to condemn the structures.

According to court documents filed in March 2022, the Peers racked up thousands of dollars in fines for failing to bring the property up to code. A judge gave the county the authority to bring the property into compliance if its owners failed to do so within 30 days of the summary judgment. And after all the legal wrangling, the county officially began demolition of the domes on Monday, with crews continuing to move debris from the site throughout the week.

While the demolition of the concrete domes marks the end of an era for Arizona’s architectural history, it also serves as a reminder of the importance of proper maintenance and safety when it comes to construction and property ownership. The domes may have been a fascinating sight, but they ultimately posed a danger to the public and had to be removed.
