CANTON -- Roman Catholic Church of Saint Mary, 68 Court St., will participate in New York Landmarks Conservancy’s ninth annual Sacred Sites Open House Sunday, May 19, from noon-3 p.m.

More than 150 of New York’s religious institutions across the state will open their doors to the public during the open house, giving visitors a glimpse inside impressive sanctuaries to view artistic and historical treasures.

Last year, 10,000 people participated in the Sacred Sites Open House with congregations showcasing their buildings and histories via lectures, musical performances, and special guided tours, and highlighting community programs that serve 200,000 annually.

“New York has a rich and diverse array of religious architecture,” said Peg Breen, President of The New York Landmarks Conservancy. “You’ll be amazed at the beauty, history and community programs you’ll discover visiting these institutions in your neighborhood or by venturing to other counties throughout the state.”

This year’s theme, Medieval to Modern: Celebrating New York’s Religious Art and Architecture, highlights the broad spectrum of historical periods, faith traditions, and styles of religious architecture found in communities throughout New York State.
