word of the week: PINNACLE
PINNACLE: a subordinate vertical structure terminating in a decorative pyramid or spire. Most often found crowning gothic buildings.
These pinnacles are decorating a top level of Chicago’s gothic-styled Tribune Tower. Bonus words: crocket and finial — both are key decorative features to many pinnacles, including the ones pictured here. A crocket is a projecting ornament, usually in the form of curved foliage, used to decorate and soften the outer angles of pinnacles, spires and gables. And a finial is the (typically) foliated ornament terminating a pinnacle.
