Langkaan is a barangay located on the south-western part of Dasmariñas in Cavite, Philippines. The name "Langkaan" came from the word "langka" meaning jackfruit; which is believed to be planted in many parts of this barangay during the 1900, the year of its foundation. Barangay Langkaan was a part of a vast hacienda during the Spanish period that's why there are numerous water systems for ricefields that can be found here. The San Agustin Dam was constructed in 1855. On the last part of the 19th century, the Spaniards erected an indigo plantation here. The stone-made grinder of indigo still exists until now and it is the mark of the Spanish influence in the place. The Spaniards are the first ones who planted sugar canes and became the primary source of income during the 18th century. Durin
