170 Fifth Avenue, southwest corner of West 22nd Street, Manhattan. Robert Maynicke designed this Beaux-Arts store-and-loft building for developer Henry Corn in 1897–98. It takes its name from an early tenant, Sohmer Piano Company, which kept its showroom and offices here. The city’s separate designation report for the Sohmer piano factory in Queens identifies the Manhattan building as a showroom address. NYC Landmarks Preservation Commission, Ladies’ Mile Historic District report, pp. 293–295.
What to look for from the sidewalk
From Madison Square, look southwest for the ribbed dome above the narrow Fifth Avenue façade. At West 22nd Street, compare the ornamented corner with the simpler stretch farther west. The district report puts the Fifth Avenue frontage at 29 feet and the West 22nd Street side at 120 feet, a difference that is easier to see from the corner. Nearby, the building at 141 Fifth Avenue offers another view of how a dome marks a corner along this stretch.
