During the Spanish Colonial period, Tomás O'Daly was granted land in the vicinity of Guaynabo and O'Daly developed it into a thriving sugar hacienda.
O'Daly and fellow Irishman Miguel Kirwan became business partners in the "Hacienda San Patricio" which they named after the chief patron saint of Ireland, Saint Patrick.
The plantation no longer exists.
The land on which it was located is now a suburb called San Patricio with a shopping mall, San Patricio Plaza.

San Patricio Plaza was designed and built by Interstate General, who leased the land to the Gonzalez Giusti family during 1964.
By the early seventies, because of the high interest rates and oil costs, Interstate General decided to sell certain properties, including San Patricio Plaza, to the Giusti family.

At that time San Patricio Plaza was a strip mall with four large buildings with shops in each of them, all united by common hallways.
The main shops were Kmart, Pueblo Supermarket, Walgreens and New York Department Store.

During the night of December 31, 1968, a fire consumed the building where Kmart was located.
As a result, the mall's management decided to enclose the facilities becoming one of the first enclosed malls in Puerto Rico.

In 1989, the mall changed its logo for the first time ever, for its 25th anniversary.

In 1994, the mall changed its logo once again; also, the mall was given a $43 million renovation and expansion.
A Food Court opened the same year.
Also, the mall's first St. Patrick's Day celebrations were held in March 1995.
The mall also introduced its "Patrick" character.

A Caribbean Cinemas location opened in 1997.

In 2003, the access control system was added to the mall.
Also, a Bed Bath and Beyond location was opened.

In late 2008, San Patricio Plaza was expanded once again, and some signage was replaced.
