Tiffany and Company Building, 1903. The origins of Tiffany & Co date to 1837 when Irish immigrant Charles Lewis Tiffany opened a stationery and fancy-goods shop. Within a few decades Tiffany's was one of the most prominent jewelry stores in the country. In 1869, the business began construction on a new store on Union Square, The new building at 15 Union Square West (it is the first full building at left in the photograph) was designed by John Kellum. Clad in an elaborate cast iron facade, it was an imposing sight on the square. The New York Times called it a "palace of jewels." Louis Comfort Tiffany, the son of the founder, became the firm's first Design Director in 1902, creating jewelry with glass, enamel, and gemstones. Tiffany & Co. moved further uptown in 1906. The building on Union Square was then home to a number of garment companies and factories before becoming the headquarters for the Amalgamated Bank in 1925. In 1952 a piece of the cast iron facade fell from the building and struck a pedestrian, who later died. Following this accident the bank hired an architect to stripe the building of its projecting ornamentation and cover all the rest. The end result was a simple (almost Brutalist) white brick structure. In 2008 the building was sold and redeveloped in condos. The original structure was surrounded by dark glass and black aluminum framing, and an additional six stories were constructed.

Lincoln Building ARCHITECT: R. H. Robertson DATE: 1889-90 STYLE: Romanesque Revival A classic example of the layered arcade design solution, a solution in which New York pioneered, the Romanesque Revival Lincoln Building is representative of an important transitional phase in the history of tall buildings. Using interior metal skeleton skyscraper construction in combination with traditional masonry bearing walls, the building is executed in limestone, granite, and brick, and has exceptionally fine carved and terra cotta detail, which includes the corner griffin, acanthus scrolls, Byzantine capitals, crisp moldings, human and lion heads.

In 1892, 27% of the country's millionaires lived in New York, when the city only made up 2% of the country's population! Welcome to the society of the Gilded Age. This tour takes its inspiration from an exhibition at the Museum of the City of New York that explores the visual culture of New York's richest residents from the mid-1870s to the start of World War One. It stops at several places, such as the old headquarters of Tiffany \&Company that are connected to the dazzling objects in the show. It also introduces you to some of the people at the center of Gilded-age society, and illuminates how-over the course of three decades- the city transformed more rapidly than ever before. It was during this time that New York became a world capital on par with London and Paris. Before the 1870s the lives of the rich and the places they frequented had been more private and understated. By the 1890s they were public and over the top: Simple brownstones gave way to French chateaux, cluttered dry good stores became palatial department stores; and grand hotels and restaurants became premiere places to entertain, outside the home. Even if shoes are more comfortable now than they were in the Gilded Age, you may find it tiring to walk this tour from beginning to end. So feel free to split it up!

The Gilded Age describes the era following the Civil War and preceding the Progressive Era. From around 1870-1900 the United States industrialized rapidly. Factories sprung up throughout the towns and cities in the Northeast and Midwest. New railroad networks and telegraph lines connected these industries and cities with the financial centers of the nation, specifically New York City. The Gilded Age is a complicated period. It saw the rise of monopolies and the creation of vast wealth. However, this wealth was limited to only a few families. Most Americans, including the millions of immigrants arriving annually, remained incredibly poor. The inequality of the Gilded Age prompted Progressive Reformers to enact laws which helped those poorer Americans. New York City represented well this "tale of two cities." In 1892, 27% of the country's millionaires lived in New York, when the city only made up 2% of the country's population! Yet the vast majority of poor immigrants arriving to the country entered through New York Harbor. While many Progressive reforms got their start in the Big Apple, the city was also the center of Gilded Age opulence.
