[4] The Municipality of Alaminos is an agro-industrial town that lies within the third congressional district of the Province of Laguna and is part of the Calabarzon.

The early inhabitants of Trenchera were believed to be insurrectionists, and possibly fugitives, who took advantage of the numerous trenches for hiding as well as for defense against the Spanish authority.

Don Cirilo Baylon, a wealthy resident of Trenchera and with good command of the Spanish language, invited Captain-General Juan de Alaminos Nivera, the Chief Executive of the Batangas.

During the program in honor of the Captain-General and his party, Don Cirilo Baylon presented the petition of the residents asking that Trenchera be made into a duly organized and recognized town.

In less than two months, the official paper proclaiming Trenchera as a new pueblo or town arrived from Lipa.

In appreciation of the Capitan-General, the new pueblo was named Alaminos in 1873 and remained part of Batangas until 1903, when it was returned to San Pablo by virtue of Act No.

[8] The Maharlika Highway passes through the municipality and is connected directly to Manila through the South Luzon Expressway.
