The land that would later become Glassell Park was originally part of Rancho San Rafael, granted in 1784 to Spanish army corporal José María Verdugo. Attorney Andrew Glassell received part of Rancho San Rafael from the lawsuit known as the Great Partition of 1871. Glassell eventually settled in the area with his family, for whom many streets, including Toland Way, Drew, Andrita and Marguarite Streets are named.

The development of Glassell Park began in the early 20th Century, as subdivisions between Verdugo and San Fernando Roads began to be sold in 1907. In 1912, the city of Los Angeles annexed most of Glassell Park, annexing the remainder in 1916. The Glassell family continued to subdivide their land, selling off what is now Forest Lawn Memorial Park during the Great Depression. The growing neighborhood was served by a line of the Los Angeles Railway, which traveled in the median of Eagle Rock Boulevard towards Eagle Rock.

Highland Park is a hilly neighborhood in the city of Los Angeles, located in the San Rafael Hills and along the Arroyo Seco. It is situated within what was once Rancho San Rafael of the Spanish/Mexican era.

Eagle Rock is a neighborhood of Northeast Los Angeles in the San Rafael Hills, Los Angeles County, California.

Eagle Rock is named after a large rock outcropping, resembling an eagle with its wings outstretched. The land was part of the Rancho San Rafael under Spanish and Mexican governorship. It was divided into parcels in 1870. It became a city in 1911 and joined Los Angeles in 1923.

Mount Washington is a neighborhood in the San Rafael Hills of Northeast Los Angeles, California. Founded in 1909, it is a historic area with one high-achieving elementary school within it. It includes the Southwest Museum and Eldred Street, one of the three steepest streets in Los Angeles.

Mount Washington was founded in 1909 as a subdivision laid out by real estate developer Robert Marsh. Marsh built the Mount Washington Hotel at the summit of Mount Washington, and the Los Angeles and Mount Washington Railway Company was soon established as a funicular railway up the hill as an alternative to constructing roads up the area’s steep hillsides. The railway operated until January 1919.
