About
The Triangle is a defined city neighborhood in Wilmington, Delaware, whose residential streets form a geographic triangle enclosed by 18th Street, Baynard Boulevard, and Broom Street—a layout conceived in the late 1800s when the area was planned as Wilmington’s first suburb. The housing stock dates predominantly to the 1920s and consists of American Foursquare, Craftsman bungalow, colonial revival, and brick semi-detached twin homes, with single-family detached houses ranging from roughly 1,500 to 3,500 sq ft and twin homes from roughly 1,350 to 2,000 sq ft. Directly across 18th Street sits Brandywine Park—178 acres established in 1886 under a Frederick Law Olmsted-informed design, listed on the National Register of Historic Places in 1976—which provides residents walkable access to the Brandywine Zoo (operating since 1905), the Jasper Crane Rose Garden, pickleball and tennis courts, a dog park, athletic fields, and the Northern Delaware Greenway Trail, a 10-mile National Recreation Trail.
