Coastal Senior College is offering three classes that do not begin until October. For those who enjoy religious architecture, Chris Glass’ Architecture of Christian Churches class will begin Friday, Oct. 7 and runs for six Fridays from 10:15 a.m. to 12:15 p.m. at the Bremen Library. The instructor is the former chairman of the Maine Historic Preservation Commission. Students will explore how Christians created new building forms from Jewish and Roman models. Looking at Turkey’s Hagia Sophia, St. Peter’s Basilica, and Gothic cathedrals, students will see their influence on smaller, local places of worship, including their influence on Maine churches.
