On 29 August 1896, Andres Bonifacio, together with Emilio Jacinto and other members of the Katipunan went into the house of Romualdo Vicencio at Sitio Balakbak (now Villa San Miguel) to prepare for the upcoming revolution against Spanish authority. In this site, Bonifacio read the last manifestation of the Katipunan before they transferred in Hagdan Bato, in the house of Felix Sanchez. This event is also known as the "29 De Agosto" and "Pinagtipunan" in which it is already named in two streets near the historic Barangay Hagdan Bato Itaas. It was in Barangay Hagdang Bato on 28 August 1896 where Andres Bonifacion issued a proclamation setting Saturday, 29 August 1896 as the date of the attack on Manila.
