[3] The town is known for its baroque church, ancestral houses, the Pinagbayanan excavation, the most important archaeological site in the municipality, and the famous Laiya Beach.

The first Gobernadorcillo was Don Camilo Perez, a prominent citizen who initiated the separation of San Juan from Rosario.

On October 28, 1883, San Juan experienced a major disaster due to continuous winds and intense storm rain.

Huge flood from the Bancoro and Bangbang Rivers hit the town resulting to the destruction of houses, drowning of livestocks and planted crops, and the devastation of the church and its convent.

The transfer of the Lumang Bayan to its present location was approved by Governor General Valeriano Weyler on December 12, 1890, during the administration of Gobernadorcillo Benedicto De Villa.

North of San Juan is the neighboring town of Candelaria, with Malaking Ilog River defining its geographical boundary.

Tayabas Bay lies east and the hills on the eastern portion separate it from the towns of Lobo and Rosario.

Despite improvements of the town's education system, parents of some students from well-off families send their children to Metro Manila for college.
