This was the tallest building in Texas from 1980-1982; surpassed by JPMorgan Chase Tower in Houston.

The plaza is home to the Jean Dubuffet sculpture "Monument to the Phantom": a fantastic fiberglass shape with red, white and blue sections in a web of black lines.

The Dubuffet sculpture's companion, Monument With Standing Beast, is located in the plaza of the Thompson Center in Chicago.

The building is similar in cladding and form to the 555 California Street in San Francisco, which was designed by the same architects.

The building contains a bank securities department, convenience shops, a restaurant, and a small auditorium on the concourse level.

The building stands on the site formerly occupied by the Baptist Sanitarium & Hospital.

On 18 August 1983, Hurricane Alicia destroyed 75% of the north-facing windows, thanks in part to a wind tunnel generated by the skyscrapers along Louisiana Street.

In 2007, the Monument au Fantôme sculpture was relocated to Discovery Green and in the following year, the plaza was rebuilt to include trees, fountains & other landscaping elements.
