'Built on Water' exhibit to open
at the museum later this year

If you visit the Ontario Museum of History & Art these days, you might see a little dust and a lot of construction.


The main reason for this  -- there are other improvements going on at our facility -- is the construction of a new exhibit:  “Built on Water: Ontario and Inland Southern California.” 


The new exhibit has been made possible by a grant from the Institute of Museum & Library Services.  


“Built on Water,” due to open this year, will be devoted to an examination of the history, present and future of water conservation in the region. 


The exhibit will focus on the regional relationship with water,  where it comes from, conservation measures under way and how we are dealing with underground pollution of water sources.  


During the construction, the museum will remain open to the public. 

Miriam Valle-Mancilla new
Museum education curator 


Miriam Valle-Mancilla has become the Curator

of Education for the Ontario Museum of

History & Art after spending much of her

education on the far side of the continent.


As the new Curator of Education, she oversees

public education programs for the museum’s

audiences, both young and old. 


Miriam, a graduate of Ramona High School in Riverside, traveled about as far away as you can in the United States when she spent her college years at Colby College in Waterville, Maine. 


It was there she began her museum career at the Colby College Museum of Art, both as a student and later as the Assistant for Access & Outreach and finally the inaugural Linde Family Foundation Coordinator of Academic Access.  


These positions prepared her well for her new position in Ontario collaborating with student groups, docents, faculty, and campus and community organizations to put on events using art and exhibitions to foster dialogue across social issues and a range of interdisciplinary topics.


“I am looking forward to meeting the

variety of audiences that seek arts and culture in their town and those who may be struggling in finding a way to connect with art,” she explained. 


Her tasks will be to plan and coordinate school tours, create educator and craft workshops and put on programs to engage the community’s rich diversity. She will also work on promoting the museum through various media and the city’s Ontario Living Magazine.
