The mansion was constructed in the early 1900s in memory of his late wife, Maria Braga Lacson, who died while giving birth to their eighth child.

During World War II, Filipino guerrillas took decisive action to prevent Japanese forces from using the mansion as a military headquarters.

For generations, Lacson's heirs consistently maintained the property, valuing its sentimental significance, especially in memory of his wife.

Today, the Lacson Ruins is considered to be one of the most iconic architectural landmarks of the Philippines, symbolizing both historical resilience and personal legacy.

It is open to daily visitors from 8am to 8pm for an entrance fee of PHP150 for adults, PHP100 for senior citizens or PWD, PHP 80 for students and free for children.
