History of the Lighthouse in the proposed CTREB logo.
Parola – Built in the 17th century, it stands guard at the mouth of Napindan Channel where the Pasig River crosses into the Laguna Lake. It became the secret rendezvous point of the Katipunan as it planned its moves to achieve Philippine’s Independence. The Parola was chosen by KKK Supremo, Gat Andres Bonifacio, as a meeting place because of its strategic location being the most accessible channel from Tondo, Manila and from the Municipios along the Pasig River and the Province of Laguna.
