Named after Luis T. Diaz who taught sports to the youth of the city.

The Coliseum opened to the public in 1971 as the main arena in the city hosting many events like Basketball games, Volleyball games, Pro Wrestling events, and Church Gatherings among others.

In the lobby, there was a plaque of Luis T. Diaz and in a room showing a lot of trophies from various sports and a picture of the 2006 Aguadilla Divas.

The Coliseum was renovated in 2005 when the city learned that the Divas were coming to play in the building.

Also the Coliseum hosts city activities, Pro Wrestling events from both IWA, Caribbean Pro Wrestling, and the WWC, Elementary, Middle & High School Graduation Celebrations.
