Park Slope | Brooklyn

Quick Profile

Boasting beautiful tree-lined streets, brownstones and a range of activities for all age groups, Park Slope is consistently ranked as one of New York’s most desirable neighborhoods. Filled with lush parks and greenery, the neighborhood is also known for its rare combination of excellent public schools, award-winning restaurants, nightlife, small independently owned businesses and community gardens.

Situated at the western slope of Prospect Park, the neighborhood is divided into different sections: North Slope, Center Slope and South Slope. Depending on who you ask, of course, the definitions of where these borders end and begin may vary (is the divide between North and Center deemed Union Street, Garfield Place, 1st Street or 3rd Street? The one between Center and South 6th Street, 9th Street, 11th Street or 15th Street?). 

Regardless of what part of the Slope you find yourself on, there’s no shortage of architectural beauty. From row houses to brownstones to mansions, the idyllic setting of the neighborhood is further enhanced by its Romanesque and Renaissance Revival styles. Case in point of this is also two of the area’s most well-known churches, Park Slope United Methodist Church and Saint Augustine Roman Catholic Church. 

Revered for its family-friendly appeal, Park Slope is often regarded as one of the best places to raise a family in New York City. That said, it doesn’t mean that parents don’t know how to have a good time... a slew of bars constantly opening in the neighborhood ranging from the high-end cocktail saloon to the dive (well, by Park Slope standards, anyway).
