Crown Building, Architectural structure in Fifth Avenue, Manhattan, US

The Crown Building is a 25-story, 416-foot-tall (127 m) building at 730 Fifth Avenue, on the southwest corner of Fifth Avenue and 57th Street. Its limestone facade has French Renaissance details, with brick and terracotta ornament and 1,363 ounces of gold leaf. The massing is divided into a nine-story base, a twelve-story shaft, and a four-story octagonal pyramidal roof. At street level, glass shop windows sit behind dark panels with gold lettering for Mikimoto and Piaget, and an arched entry on the left bears a smaller "THE CROWN BUILDING" inscription with three gold statues in niches above it.

The building was finished in 1921 following plans by architectural firm Warren and Wetmore, who also designed Grand Central Terminal. During the 2010s, a major renovation transformed the upper floors into hotel rooms and residential units.

The name was adopted in 1983, when the illuminated upper floors were likened to a crown; the building had been the Heckscher Building since 1921. At street level, gold lettering for Mikimoto and Piaget sits above the shop windows, and the arched side entrance carries three gold statues in niches.

The building sits at a busy intersection and is easily visible from the outside during daytime. Visitors can explore the street level, while upper areas remain accessible only to guests and residents.

The building holds 1,363 ounces of gold leaf, applied to the facade and its ornament. The name dates from 1983, when the illuminated upper floors were likened to a crown. The pyramidal roof is octagonal and rises four stories above the shaft.
