A small-town feel is one of the reasons for Crown Heights’ increasing popularity. Superb brownstones and limestone houses dating back to the early 1900s, when Eastern Parkway was a coveted upper-class address, have played a large part in the area’s rise. (You can also find handsome pre-war apartment buildings.) Laying just east of Prospect Heights, with Washington Ave. serving as demarcation, Crown Heights has long been the diverse, energetic home to thriving Caribbean, African-American, and Jewish communities. This is the kind of place where you can pick up a terrific meal then work it off with a tennis game at Lincoln Terrace Park.
