Insurance Company of North America Building
- Address: 1600 Arch St
Upon its completion in 1925, the 16-story, steel-frame, brick-and-stone INA Building at 1600 Arch Street became the company's ninth home office. It has now served in that capacity longer than any of its predecessors, and it is the only one of the nine that is extant. Significantly, it was planned and completed during Benjamin Rush's tenure as president of the company and thus is closely identified not only with INA's recent accomplishments but with Rush's systematic classification of marine risks and the firm's rise to preeminence in inland marine insurance. Virtually unaltered externally, the building is in excellent condition and retains many important original interior features and continues to house the company's executive offices. Designed by Stewardson and Page and constructed by Stone & Webster, Inc., the east-facing building rests on belled concrete piers between Arch and Cuthbert Streets and represents a combination of Second Renaissance and Georgian Revival styles. Above a basement and subbasement a 2-story, Stonington Pink Granite ashlar base rises approximately 65 feet and is topped by a 10-story red brick center section laid in Flemish bond and a 4-story crown faced with white Indiana limestone. - NRHP Registration, May 1977
