The Houston Rockets season may be over, but sports fans can still celebrate this month. Supporters of all things H-Town sports and the Astrodome are encouraged to don their sports apparel (or anything “Astrodome related,” according to the invitation) and attend the unveiling and dedication for a new Texas State Historical Marker for the Eighth Wonder of the World.

The event will take place at 3 pm Tuesday, May 29 on the west side of the Astrodome at NRG Park. Parking can be accessed through Gate 9 at Westridge and Kirby. The lot will open at 2 pm. Guests can expect brief remarks from multiple speakers including Harris County Judge Ed Emmett, who has been a tireless advocate of repurposing the building, and Dene Hofheinz (daughter of Roy Hofheinz), who is most associated with the creation of the Astrodome. There will also will be followed by the marker unveiling.

It’s been a banner year for Astrodome supporters. In February, the Harris County Commissioners court approved a $105 million project that would reconfigure the Astrodome into an event center. The plan involves raising the ground level up two floors, which would create a parking garage with 1,400 more parking spots.

And in March, diehard Dome fans were treated to a Domecoming, where locals were allowed to tour the facility one last time before construction began, creating an opportunity for priceless selfies.

This month’s dedication is the result of efforts of Harris County Historical Commission member and Heritage Society program director Mike Vance, and Mike Acosta, a team historian for the Houston Astros. The two longtime researchers of Houston sports history have worked for years on efforts to preserve and reimagine the iconic Astrodome.

The marker designation makes the building a Recorded Texas Historic Landmark, judged by the state to be both historically and architecturally significant. This is in addition to the Astrodome's status as a State Antiquities Landmark and the title of being on the National Register of Historic Places. The marker is sponsored by the World Champion Houston Astros, and is also supported by the Harris County Sports & Convention Corporation and NRG Park.
