On October 29, 1901, the National Museum of the Philippines was established.
Here is a part of the history of the National Museum from gov.ph:
The National Museum of the Philippines can trace its history to the establishment of the Museo-Biblioteca de Filipinas, established by a royal order of the Spanish government on August 12, 1887. It opened on October 24, 1891 at the Casa de la Moneda on Calle Cabildo in Intramuros, then home of the Philippine Mint, later moving to Calle Gunao in Quiapo. The Museo-Biblioteca was abolished in 1900 at the onset of the American occupation of the Philippines, and what is considered the direct precursor of the National Museum, the Insular Museum of Ethnology, Natural History and Commerce, was soon afterwards established under the Department of Public Instruction by the Philippine Commission on October 29, 1901. One of the reasons for the creation of the Insular Museum was to complement the Bureau of Non-Christian Tribes, and it was subsequently integrated with the Bureau of Ethnological Survey under the Department of the Interior.
