The History

Colt Stadium was built as a temporary facility to host the Houston Colt .45s, a newly formed MLB expansion team. The stadium served as the team’s home for three seasons, from 1962 to 1964, until the completion of the Astrodome. While it was always intended as a temporary structure, Colt Stadium played a significant role in introducing Major League Baseball to Houston.

The stadium was dismantled after the team moved to the Astrodome, but its legacy is remembered as a stepping stone for professional baseball in Houston.

Design and Features

Colt Stadium was a basic open-air ballpark with simple, utilitarian design features. It had a standard diamond layout with uncovered bleachers and grandstands, offering unobstructed views of the field. The stadium lacked many of the amenities that would become standard in later ballparks, reflecting its temporary nature.

Despite its simplicity, Colt Stadium was known for its challenging playing conditions, particularly the intense heat and humidity of Houston’s climate, and the presence of mosquitoes, which added a unique element to the games played there.


Given its status as a temporary facility, Colt Stadium underwent few, if any, significant renovations during its brief existence. The primary focus was on maintaining the basic functionality of the stadium until the completion of the Astrodome.


Colt Stadium’s facilities were basic and sparse, in line with many temporary sports venues of the time. Concession options were limited, and the seating was functional but not particularly comfortable. Despite these limitations, the stadium provided Houston baseball fans with their first opportunity to experience Major League games in their city.

The lack of advanced facilities highlighted the need for a more permanent and modern stadium, which would be realized with the construction of the Astrodome.
