Barangay Arkong Bato is a historical barangay named after the famous stone arc landmark that demarcates the boundary between the barangay and Malabon's Brgy. Santulan. The notable stone arc was built by the Americans in 1910, originally as a boundary between Rizal and Bulacan province. Residents celebrate the Sta. Cruz fiesta every May 1. Some of the barangay's landmarks include the Arkong Bato Chapel and the statue of Delfin Belilia Navarese.
