[Bethesda Fountain.]Bethesda Terrace, 1870s. Photo by Augustus Hepp from Museum of the City of New York

A few years after Central Park was completed, Augustus Hepp, the head gardener for the park was commissioned by the U. S. Secretary of State William Maxwell Evarts to create a portfolio of images – which appear today in a striking blue color. These images, available in the collection of the Museum of the City of New York, were originally used to American politicians to “convince their Continental counterparts that New York was not just an industrial powerhouse but also a mature and cultured city that could create great urban parks on par with those in Europe,” writes Sean Corcoran from the Museum. These photographs were even given as a gift to the French government in 1879.

The images are digitized from 40 large format cyanotypes, and the chemical process gives it the blue tinge. Among the photographs, you’ll see the original Romanesque revival-style Metropolitan Museum of Art in Central Park (which is still enclosed within today’s Neoclassical building), Belvedere Castle, Bethesda Terrace, and much of the landscaped grounds.

You’ll also see buildings and bridges that no longer exist, like McGown’s Pass Tavern that closed in 1915, the original boathouse designed by Central Park designers Frederick Law Olmstead and Calvert Vaux, the lost Marble Arch (literally buried), and the first version of the Gapstow Bridge, an iron and wood structure by Jacob Wrey Mould. It was replaced in 1897.
