Situated in Washington, DC, the Pope John Paul II Cultural Center offers a unique architectural environment. Creating St. Peter’s is a traveling Vatican exhibit that strives to illustrate the dynamic history of Rome’s status at the heart of the Christian world through the display of art, historical documents and ancient objects. The exhibition’s centerpiece is Michelangelo’s 18-foot tall wooden model for St. Peter’s dome that intricately details the interior and exterior surfaces of the 500-year-old structure. Spaces to house this important installation required significant modification to meet the Vatican’s strict traveling exhibit criteria. The Dome room was altered to accommodate the model’s unusual height as well as to meet stringent temperature, humidity and lighting requirements. Similarly, the Center’s second-floor exhibit hall was enclosed with a glass curtain wall system to create an appropriate environment for the display of historically-significant artifacts including 17th century engravings and papal portraits .
