The ancient Kingdom of Namayan (also called the Kingdom of Sapa, Maysapan or Nasapan, and sometimes Lamayan-both references to its capital) was one of three major kingdoms that dominated the banks of the Pasig River and the coast of Laguna de Bay before the Spanish conquest in the 16th century. Namayan was the oldest of the three kingdoms, predating the kingdoms of Tondo and Maynila.
