Crown Heights – a neighborhood once stigmatized for its race riots of the early 1990s – is now getting royal treatment for its exquisite architecture.

The city Landmarks Preservation Commission today approved a 610-building historic district in the Brooklyn neighborhood, from Bergen Street to the north, Eastern Parkway to the south, and Nostrand and Brooklyn avenues to the west and east, respectively.

It’s part of a plan the designate more than 1,700 buildings in the neighborhood’s north end as landmarks. It was pushed by the civic group Crown Heights North Association to improve property values and offer protection from developers.

An adjoining 472-building historic district was designated in 2007, and LPC today began studying adding a third adjacent district with 640 buildings.

The homes are largely row houses, freestanding homes and apartment houses built between the 1870s and the 1920s and designed in many styles including neo-Grec, Queen Anne, Colonial, Gothic and Medieval Revival.

“The neighborhood is really an exquisite mosaic of remarkably well preserved examples of architectural styles and building types,” said LPC Chairman Robert B. Tierney, who praised the Crown Heights North Association for organizing the support for the district and stewardship of the buildings.

Most of the land was once part of a farm owned by the Lefferts family, who auctioned off the site as 1,600 lots starting in the 1850s.
