Park Avenue is a major thoroughfare in New York City, known for its wide, tree-lined streets and elegant buildings. It runs through the borough of Manhattan, stretching from 42nd Street in the south to 132nd Street in the north. The avenue is famous for its upscale residential buildings, corporate offices, and cultural institutions, making it a significant part of the city's landscape. Originally named Fourth Avenue, Park Avenue was renamed in the late 19th century after the construction of the Park Avenue Tunnel, which allowed trains to run underground. Today, it is recognized for its vibrant atmosphere, featuring art installations and seasonal decorations, particularly during the holiday season.
