San Pablo is one of the oldest documented settlements in the Philippines. In 1586, Captain Juan de Salcedo arrived in the village of
Sampaloc, an upland community of Tagalog and Aeta. Geographically, the city is the heart of the
Laguna Volcanic Field, which explains the abundance of unique geological structures such as the
crater lakes, hills and others. Politically and economically, San Pablo is one of the most prosperous cities in the country in the early 20th century, owing to its main produce of coconuts. It is also the first city in the province of Laguna as established by Commonwealth Act no. 520. The city is also home to the see of the Roman Catholic Bishop of San Pablo, a diocese which oversees catholic churches in the province of Laguna. As expressed in City Ordinance (CO) 2018–53 by the local government of San Pablo, the San Pablo Heritage zone was established to preserve and enshrine the legacy and history of the city. == Boundaries ==
