The History

Opened in 1965, the Astrodome was the first of its kind – a massive, air-conditioned indoor stadium with a domed roof. Its construction was a groundbreaking achievement in engineering and architecture, setting new standards for sports venues worldwide. The stadium was initially home to the Houston Astros and later hosted the NFL’s Houston Oilers, among other sports teams.

The Astrodome’s closure for regular sports events in 2006 marked the end of an era, as newer, more modern facilities began to emerge. However, its legacy lives on as a pioneering structure in stadium design.

Design and Features

The Astrodome was celebrated for its futuristic design and technological innovations. It featured a domed, clear roof that allowed natural light to illuminate the field, which initially had natural grass. The introduction of AstroTurf, a synthetic turf, was a direct result of the stadium’s indoor environment, as the grass could not grow adequately under the dome.

The stadium’s colossal size and air-conditioning system were considered marvels, offering fans a comfortable viewing experience regardless of Houston’s weather.


Over the years, the Astrodome underwent several renovations to enhance its functionality and capacity. These included the installation of thousands of additional seats, upgrades to the luxury boxes and press facilities, and the installation of AstroTurf.

These renovations aimed to keep the Astrodome at the forefront of modern stadium design, although they could not fully address the challenges posed by the evolution of sports venue standards in the years following its opening.


The Astrodome offered a range of facilities that were advanced for its time. The concessions provided a wide array of food and beverage choices, and the seating was designed for optimal viewing comfort. The stadium also featured ample parking and easy accessibility, making it a popular destination for sports fans in Houston.

While its amenities may have been surpassed by newer stadiums, the Astrodome was a pioneer in providing a full-fledged entertainment experience for sports fans.
