I missed the challenge on Architecture so I thought I would share these shots from Boston.

3 buildings with sun,  arch way,  arches by the water, the brigde, church, church door, clock tower, custom house, reflection of church,  old building at Boston College .  
Some cool Gargoyles  second one,  bars on a window,  cool arches.  There is a grasshopper on top of this building grasshopper faraway see the closeup.  This building had some cool shapes  building a steple and last of all  the subway entrance and the  park street subway. And my favorite sky line at sunset
