Pasig City

·	Under the rule of Raja Sulayman, Pasig River was a great source of wealth not only due to its aquatic bounty, but also for the riches and exotic treasures it brought from far and near, carried by the junks and boats that docked by Manila and coursed upriver.
·	On August 28, 1896, Valentin Cruz, Katipunan leader of Pasig, was in Balakbak Hills near Hagdang Bato in Mandaluyong where Bonifacio issued his formal war manifesto calling on all towns to rise in arms and attack intramuros the next day ay midnight. On that occasion, Cruz was prompted to general de Brigada at the young age of 31.
·	The original Pasig was a vast territory extending as it did from Montalban 20 kilometers to the north (being in olden times a barrio of San Mateo) and as far south as Bai more than 50 kms. as the crow flies.
·	In 1993, the enrollment in Rizal High School was 16,360 students already and then it gained recognition from the GUINNES BOOK OF RECORDS for being the biggest Secondary School in the world, in terms of population.
