Glendale that straddles Myrtle Avenue is the primary business district and has a mix of semi-detached, wood frame, single-family houses as well as a number of multi-family dwellings and townhomes. The housing stock here often dates back to the late 1800s/early 1900s and as a result, a significant number of them are made of yellow Kreischer brick much like similar, landmarked buildings in neighboring Ridgewood. The western or "lower" part of Glendale has three national historic districts and includes the neighborhoods of Evergreen (near and around Evergreen Park) and Liberty Park, which is bordered by Cypress Hills Street, Cooper Avenue, 61st Street and cemeteries to the south.

The cemeteries include Cypress Hills, Lutheran All Faiths, Salem Fields, Mount Lebanon, Mount Carmel, New Mount Carmel, Beth El (New Union Field), Mount Neboh, and Union Field. Some of these cemeteries are the resting places of many famous people, including Jackie Robinson, Mae West, and Harry Houdini, at whose tomb devotees gather each year on Halloween to see if he can pull off the ultimate escape trick and return from the grave. Cypress Hills Cemetery is the site of the New York City Police "Arlington" and also contains the graves of Confederate soldiers who died in local prisons and hospitals.
