After the restoration, it became the venue for these historical events :
The second session of the United Nations Economic Commission for Asia and the Far East.
The second session of the United Nations Food and Agriculture Organization in 1948.
The first meeting of the Southeast Asian Union [ The Baguio Conference of 1950 ], which was conceived and convened by President Elpidio R. Quirino.
The succeeding presidents would frequently escape the heat and the bustle of Metro Manila in exchange for Baguio’s relaxed pace and cooler climate. This made the Mansion House their summer retreat of choice, each leaving their own mark by adding various structures to the home.
On 16 January 2009, the board of the National Historical Institute, known today as the National Historical Commission of the Philippines [ NHCP ], declared the Baguio Mansion House as a National Historical Landmark through Resolution No. 1 s. 2009.
It recently underwent a major renovation to make way for priceless items and memorabilia from our former leaders, offering an intimate glimpse of the history and heritage of the Philippine presidency.
On 27 July 2024, the Baguio Mansion House opened its doors for the very first time as the Presidential Museum in the country’s summer capital.
