ago, Sagayaden was a forest land, inhabited
by industrious and peace-loving people.
It has been known by several names,
one of which is Pimmayong which was
derived from umbrella-shaped hills nearby.
And to trace its historical growth,
this is how Sagayaden got its name.
In the western boundary of the barangay
are two hills namely Lanag and Southern
Pila. The people of Sagayaden inhabited
these hills forming two sitios. If God
had showered his grace all over the
land, it is cognizable that this valley
where abundant crops of extra ordinary
sizes are grown year round. The inhabitants,
thankful of these blessings, revere
its history by naming the place Sagayaden
from Nagayad Ti Pagay, Natnataeng ken
Thereafter, the two sitios united themselves into the new barangay of Sagayaden. Because water supply is so difficult in the hills, they moved eastward where water supply was more abundant. It is favorable too, for their products are easily transported to the poblacion. Its people recognized its famous leaders, namely, Mr. Alejandro Piros and Mr. Marcelino Sayaboc. They were responsible in founding Barangay Sagayaden. They sowed the seeds of peace and cooperation. It is known to many as the vineyard of peaceful people. A tactful leader and a cabicilla of wealthy land owner, Mr. Alejandro Piros was an instrument in the purchase of some land from the wealthy land owner, Don Modesto Serrano.
Barangay Sagayaden is located at the boundary of the municipality. It is three kilometers away from the town proper. It is almost a kilometer west of the national road. It is bounded by the north by Barangay Bonifacio, the west by Barangay Pila, in the south by Barangay Refaro and in the east by Barangay Labnig, both of the Municipality of San Juan and Barangay Cuancabal. It has a total land area of 432,761 sq. meters.
