According to a source, Colegio de la Milagrosa (sorry for the younger batches, the author simply couldn’t let go of the old name) was a former cigarette factory. The land of the said factory was eventually donated to the nuns (the author is not sure of these nuns already belonged to the Daughter’s of Charity).
On 1905, Howard Taft visited Sorsogon. A picture was taken in the town’s pier wherein the background was a factory. It seems that it’s the same perspective where Colegio de la Milagrosa is now standing.
One can notice that the factory is very near to the shore. But there’s a possibility that the shore moved further to the sea across the years. Anyway, I leave this to those who were there (meron pa kaya).
The original picture, and other old pictures, can be found here.
