CHICAGO (JTA) — Just three stories high and hemmed into a small 5,000-square-foot lot, the building at 16 S. Clark St. is a small jewel box situated amid this city’s dense urban fabric. Exuding an aura of cool simplicity, the structure’s facade is composed of glass, metal and concrete planes. Its name is etched in delicate gold lettering: Chicago Loop Synagogue. Perched above the synagogue’s front door, a two-ton sculpture extends over the sidewalk. Created by Henri Azaz in 1963, the work consists of bold letters tumbling over each other spelling the priestly benediction. A pair of massive hands emerges from the words, sloping downward as though placing a blessing on the heads of all those who enter.
