Four Corners

Four Corners at the intersection of Broad and Market Streets in Newark, Essex County, New Jersey, United States, is the site of the city's earliest settlement and the heart of Downtown that at one time was considered the busiest intersection in the United States. A twenty-two-square-block area radiating from the crossroads is a state and federal historic district.
The crossing became the center of the town soon after establishment in 1666; the home of founder Robert Treat was located at the southwest corner. During the next centuries it remained the focal point of the city which grew around it. By 1834 the United New Jersey Railroad and Canal Company had established a terminal to the south and in 1869 the Newark and New York Railroad had one to the north. During the period of massive expansion at the start of the 20th century, the district became the city's modern business district, and site of its first skyscraper built by the Fireman's Insurance Company at the southeast corner in 1910. The Newark Public Service Terminal on Broad Street opened in 1916.
