'A medieval thought'

 Boston's Trinity Church

“Trinity Park lies directly across from the  {Boston Public} library, Trinity Church rising like a medieval thought amidst the glass and steel towers.”  

― Writer Nick Flynn, from his memoir Another Bullshit Night in Suck City, about his difficult early life in the Boston area. His mother killed herself and his father was homeless.

Trinity Church, designed by Henry Hobson Richardson and built in 1872-77  on the north side of Copley Square, in Boston's Back Bay neighborhood, is the birthplace and archetype of the Richardsonian Romanesque style, with a clay roof, polychromy, rough stone, heavy arches and a massive tower. The style  became popular across the United States, especially for  such institutions as schools, libraries and churches.
