The Agoncillo–Mariño House is a historic Spanish Colonial Era residence, constructed by Marcela Agoncillo’s grandfather, Don Andrés Mariño, around the 1780s, standing as one of Taal’s oldest homes. It was subsequently transformed into a public museum known as the “Museo nina Marcela Mariño and Felipe Agoncillo,” now recognized as one of the national shrines overseen by the National Historical Commission of the Philippines.
