The Don Lorenzo del Rosario House, also known as Casa Bizantina, is a heritage house museum originally located at San Nicolas, Manila. It was transferred and reconstructed in 2009 at Las Casas Filipinas de Acuzar, Bagac, Bataan. It was designed by a Catalan architect Joan Josep Jose Hervas y Arizmendi, in 1890. It is the only existing building designed by the Architect Arizmendi in the Philippines. In addition to that, it was cited by Tribune magazine in 1939 despite its neglected state.
