Bulusan's other ancient walls

Few know that these walls exist right in the Poblacion along Sabang Road. Some in the know say that these predates the Spanish walls at the chuchyard. Some say that this is the trail to an earlier Bulusan settlement. Nobody is really sure. But what can be noticed at first sight is how these rocks can hold together for so long without crambling down with little or no cement. Tried pulling one rock myself but the adhesive material (whatever it is) is really keeping the rocks together.  Remarkable technique of stacking of the rocks!

This is the trail being used now in going up to Kapilihan. Not easy to spot because it runs perpendicular to the main road. It is located just meters away from the spillway.
