 Passage 2:Peru – country located in western South America, on the Pacific Coast, north of Chile. Peruvian territory was home to several ancient cultures. Ranging from the Norte Chico civilization in the 32nd century BC, the oldest civilization in the Americas and one of the five cradles of civilization, to the Inca Empire, the largest state in pre-Columbian America, the territory now including Peru has one of the longest histories of civilization of any country, tracing its heritage back to the 4th millennia BCE. The Spanish Empire conquered the region in the 16th century and established a Viceroyalty, which included most of its South American colonies. After achieving independence in 1821, Peru has undergone periods of political unrest and fiscal crisis as well as periods of stability and economic upswing.
 Passage 3:The platform featured an oak ticket booth and an oak-cased clock from the Self Winding Clock Company. Evidence of the now-demolished ticket booth is a Beaux Arts design engraved on the ceiling. The platform also features station tiling by Heins & LaFarge, who designed the station plaque in a sans-serif font. The walls are made of small white rectangular tiles, except for the bottom , which is marble. There are also fifteen ceramic plaques toward the top of the platform wall, all of which depict a sloop in the New York Harbor to signify the station's location and use. The top of the wall also includes festooned garlands and station monograms, in addition to ceramic trim where the wall intersects the ceiling. The station artwork on the original exit's landing is a 1990 mural, "South Sails", by former MTA Arts & Design director Sandra Bloodworth. During the 2004 Finding Of No Significant Impact for the station, it was determined that the station was eligible for National Register of Historic Places status.
