The recorded history of Yorkville begins in the 17th century when it was a tiny hamlet on the Boston Post Road, which ran northward from New York, which at the time only occupied the tip of Manhattan. It was long the province of farmers and wealthy landowners, including merchant Archibald Gracie, whose riverfront estate is now the official residence of New York’s mayor. In the 19th century, the area slowly began its transformation into the urban neighborhood we see today. Like most such transformations in New York, these changes were largely propelled by transportation improvements. In 1834, the New York & Harlem Railroad (later the New York Central) opened a station at 86th Street and Park Avenue, and in the 1850s, horsecar lines were completed along Second and Third Avenues. This opened the neighborhood to low-density residential development, a few remnants of which remain, including 412 East 85th Street. After two major economic depressions (in 1857 and 1873) and the Civil War, the area was finally primed for a major wave of construction in the late 1870s with the arrival of mass transit. The Third Avenue elevated train was completed in 1877-78, and the Second Avenue elevated in 1879-80. In a relatively short period, the Upper East Side was entirely built up, and the elevated trains segregated the area along ethnic and economic lines. West of Third Avenue, wealthy homeowners established the city’s most exclusive neighborhood, while east of Third Avenue became a thriving immigrant community (already known as Yorkville by the 1860s), which in many ways was a second-generation immigrant neighborhood—a place that recent arrivals aspired to live after filtering through the older, more congested downtown districts like the Lower East Side. Its housing stock was largely composed of tenements, but they were brand new and built after the Tenement Law of 1879 (the “Old Law”), so were subject to improvements. There were abundant employment opportunities, notably in the neighborhood’s breweries and at the Steinway piano factory in Queens, which was a short ferry ride away from the foot of East 92nd Street. The largest and perhaps most visible immigrant group in Yorkville was the Germans. Already an established presence in New York following a wave of immigration in the 1840s, they began moving uptown from their Lower East Side settlement, Kleindeutschland (Little Germany) to Yorkville, which by the turn of the century had become New York’s foremost German neighborhood. They brought with them many of their institutions, including churches and benevolent organizations, as well as cultural and commercial enterprises, such as beer halls and music societies. East 86th Street became the community’s main artery. Other groups had micro-neighborhoods in Yorkville, as well. Czechs began moving to the area in the 1880s and settled mostly between 71st and 75th Streets. Hungarians arrived around the turn of the 20th century on East 79th Street, though their institutions can be found throughout the neighborhood. Yorkville’s heyday as a distinct immigrant community was relatively short-lived. German immigration to New York peaked in 1882, and by the early 20th century, Yorkville’s Germans were already moving farther afield, using the recently built subway to access newer, more affordable neighborhoods in the outer boroughs. At the same time, anti-German sentiment during World War I led many Germans to downplay overt displays of national heritage. The Second Avenue and Third Avenue elevated trains were demolished in the 1940s and 1950s, respectively, removing one of the major boundaries between Yorkville and the rest of the Upper East Side. The neighborhood has seen its share of redevelopment since then, with large apartment buildings towering over the tenements. The recent opening of the Second Avenue subway re-established one of the area’s transit links, but may also put additional pressure on Yorkville’s surviving historic resources.

In the closing decades of the 19th century, New York underwent a profound physical and cultural transformation. Fueled by the wealth of the exploding financial and manufacturing sectors, the city rapidly evolved into a world-class metropolis. The bold ambitions of civic and business leaders, architects, and engineers of the era manifested in landmarks such as the vast Cathedral of St. John the Divine, the stately U.S. Custom House, the towering Municipal Building, and the original terminus of New York City’s first official subway line—the ornate City Hall stop. The sweeping interior spaces common to all of these structures, and hundreds of others, depended upon a venerable Mediterranean building technology adapted to contemporary American construction: arched tile ceilings—or vaults—that were not only self-supporting but could also bear the weight of floors or roofs above them. These vaults were designed and built by a single New York firm, founded by Spanish immigrant Rafael Guastavino (1842-1908) and later headed by his son Rafael Jr. (1872-1950). The Guastavinos’ patented system for building domes and vaults involved multiple layers of thin ceramic tiles bonded with quick-drying mortar. The resulting structures were not only exceptionally strong, but also lightweight, easy to build, and inherently beautiful, thanks to intricate patterns of exposed tile that formed finished, decorative surfaces. Guastavino vaults figured prominently in more than 1,000 projects across the nation, including 200 in Manhattan alone. During its 73-year history, the Guastavino Company helped build some of the most impressive interior spaces in America—veritable palaces for the people. This list based on MCNY's exhibition Palaces for the People, contains many of Guastavino's masterpieces in the five boroughs, both those that remain and those that have been lost to the wrecking ball.

Take a look through some of our partners' favorite stories from this year.

Many houses of worship on the Upper East Side are devoted to a myriad of individual traditions, which contributed to our neighborhood’s multi-ethnic identity. The Church of the Holy Trinity, at 316 East 88th Street, is somewhat unique because it was not built to support just one of these traditions, but welcomed everyone. Holy Trinity was conceived as a “Settlement Church” by Serena Rhinelander, a member of the prominent Rhinelander family, which held vast land in Yorkville and was known for real estate and philanthropy in the neighborhood. Originally founded in midtown in 1864 as a Protestant Episcopal Church, Holy Trinity was designed as a community complex by the architectural firm Barney and Chapman. Their work on the Holy Trinity includes a French Gothic bell tower, which the NYC Landmarks Preservation Commission calls an “outstanding example of the French Gothic spirit adapted to a late Nineteenth Century brick and terra-cotta religious structure,” and a French renaissance Parish house that has served as a community oasis since it opened in 1897. Then as now, the Parish House offers an auditorium, classrooms, and meeting rooms serving the needs of neighbors of all ages. Holy Trinity was designated a New York City landmark in 1966 (so one of the City’s first) and added to the National Register of Historic Places in 1979
