The Sacred Sites Open House Weekend will be held May 18 and 19 in the Buffalo area, local organizers said.

This year will mark the third for the statewide event, which locally will feature First Presbyterian Church, Blessed Trinity Catholic Church, Corpus Christi Catholic Church, Buffalo Religious Arts Center and the Chapel at Forest Lawn.

Local organizations have begun a new collaborative effort, Buffalo Alliance for Sacred Places, organizers said. The local churches will join other religious sites in New York State in opening their doors for the tour weekend.
