Temescal is one of the oldest neighborhoods in Oakland, California, located in North Oakland, and centered on Telegraph Avenue. The neighborhood derives its name from Temescal Creek, a significant watercourse in the city. History Temescal was originally a separate unincorporated village that had built up around the estate of Vicente Peralta, which was located near the modern intersections of Telegraph Avenue and Claremont Boulevard. (Vicente's estate was part of the larger Peralta Grant that spanned 44,800 acres of land in the East Bay.) The name came from the creek upon whose banks Peralta had established his home. The word temescal derives from the word temescalli/temazcalli (various transliterations), which means "sweat house" in the Nahuatl language of the Mexica ("Aztec") people of Mexico. It is surmised that the Peraltas or perhaps one of their ranch hands (vaqueros) had seen local indigenous (Ohlone) structures along the creek similar to those in other parts of New Spain which were called temescalli. A post office opened in North Temescal in 1877; the name was changed to Alden in 1899. The name commemorated S.E. Alden, farmer and landowner. In 1908, the Alden post office was designated as Station E of the Oakland post office. In 1897, the residents of Temescal voted to join the City of Oakland in an effort to gain access to higher quality public schools and police services. At the time that the City of Oakland annexed Temescal, Temescal was considered to consist of all land north of 36th Street (the northern bound of the City of Oakland at the time) between the Emeryville city limit to the west and Broadway to the east. Temescal has long been an important junction of several principal thoroughfares: Telegraph, Claremont, and Shattuck Avenues, and 51st Street. The earliest telegraph wire from Oakland to Sacramento went through the area, up Claremont Avenue and over the hills at Claremont Canyon. Temescal was the site of agriculture, cattle grazing and greenhouses when, in the 1890s, an opera house was built in parkland north of the creek crossing at 51st street. The area grew and was developed into Idora Park, the earliest "trolley park" in the East Bay. In 1929 the amusement park was closed and was razed in 1930. A plan to build mid-rise apartment blocks called the Midtown District fell through, and a tract of storybook houses was built on the site between 1930 and 1934. It
