Maryknoll Ecological


At the Maryknoll Ecological Sanctuary, we promote earth consciousness, spirituality and action. We welcome you to learn with us and build a deeper connection with the earth we live in.


The Maryknoll Ecological Sanctuary promotes a holistic understanding of the Earth. This is gleaned through scientific data, ancient traditions, and indigenous cultures and guided by the world religions and modern spiritualities that reconnect all of creation with the Eternal Spirit.


The Maryknoll Ecological Sanctuary envisions a mutually enriching Earth-human relationship that will enable future generations to care for a beautiful and thriving planet capable of supporting life with justice and peace for all. 



The Maryknoll Sisters arrived in the Philippines in 1926. Three years later, a Maryknoll convent was built in Campo Sioco, Baguio City, originally intended as a vacation and retreat house.

In 1933, seeds of the Maryknoll Convent School were planted when a Syrian mother living in Baguio pleaded with the Sisters to tutor her three children. More pupils were added the following year and thus began what became Maryknoll Convent School, with Maryknoll Sisters as principals & teachers with only 20 Filipino & international students per class, renamed Marishan School in 1977. Maryknoll Convent School from Nursery to Grade 7 and Marishan School from Nursery to Grade 6 together had 66 years of existence from 1933 to 1999.

In July 1990, a 7.8 earthquake hit Baguio city, damaged the Maryknoll Convent beyond repair, and partly destroyed the school. The devastation in the city prompted the Maryknoll Sisters to examine the community's most urgent need in an ecological context. In November 1991, sixteen months after the earthquake, the Maryknoll Sisters created the Maryknoll Sisters Center for Justice, Peace, and the Integrity of Creation, popularly known today as the Maryknoll Ecological Sanctuary.

Since it formally opened in 1999, it has provided integrated, non-formal earth education to teachers and students in elementary, high school and college levels, to religious congregations, and to the general public. It continues to work towards articulating a new cosmology, or an understanding of the earth and its meaning, gleaned through scientific data, ancient traditions, indigenous cultures, the world traditions, and contemporary spirituality that move us to re-connect both with nature and God's Eternal Spirit. It was renamed Maryknoll Ecological Sanctuary in 2013.
