The school grounds and the mansion lights up during the Christmas season with a grand opening called "Daigon Slash Sigaboom."

Built in 1937 by Don Emiliano Lizares for his wife Concepcion Gamboa and their two sons and three daughters, the mansion has three floors, a basement and an attic.

When World War II broke out, the family left for a safe hiding place in Pototan, Iloilo.

In 1950, Don Emiliano Lizares died and his widow left for Manila, leasing the mansion to a businessman who turned it into a casino.

The 123rd act of the 10th provincial chapter states: “We ordain that the DPP move towards integrating all existing educational institutions of the [Philippine Dominican] Province within the two venerable and historical educational institutions, that of Letran (1620) and UST (1611) in the event that UST is transferred to the jurisdiction of the Province.

The upper half of the outer circle bursts with the words "angelicum school iloilo" in gold letters using Old English type.

The lower half of the outer circle carries the words "ILOILO CITY" and the institution's foundation year “1978” also in gold letters using Arial type.

The multi-ray sun, rendered in gold, is symbolic of St. Thomas Aquinas, Doctor of the Church and patron saint of Angelicum School Iloilo and of all Catholic institutions in the world.

The open book inscribed with the word VERITAS represents the quest for excellence especially in the search for the truth, which is Jesus Christ, just as all knowledge should begin and end in God — the alpha and the omega.

The lower part of the escutcheon, which is the largest, is the black-and-white Dominican cross and shield representing the Order of Preachers which established the school and whose charism and zeal for the Truth are deeply ingrained and manifested in the school's activities as well as in its vision, mission statement, philosophy and objectives.

The school's three-word motto of "CARITAS," "JUSTITIA" and "FORTITUDO" in black letters in Arial, encased in a white banner spread under the escutcheon, inspires everyone who passes through the portals of Angelicum School Iloilo to have a great love of God and neighbor, a strong sense of justice toward others, and an unyielding fortitude to overcome all odds in the service of God and neighbor.
