A complete history of Comanche Lookout was published in the Index of Texas Archeology in 1998. 

Comanche Hill is a prominent landmark in northeast Bexar County. As such, it carries with it folklore and legendary "baggage" that may or may not be historically correct, e.g., the Mormon massacre and buried gold. The fact that Comanche Hill lies adjacent to the old Nacogdoches-to-Bastrop-San Antonio Camino Real (Royal Road) indicates that the lookout was a significant and frequently used landmark during the eighteenth and nineteenth centuries (McGraw et al. 1991).

Texans have a long and contentious history with the Comanche.

The modern history of the park began in 1923 with its sale to Colonel Edward H. Coppock:

As the survivor, Gustav Reeh eventually sold the southern three-quarters of Comanche Hill parcel to
Colonel Edward H. Coppock in February 1923 for a sum of $6,000. Colonel Coppock retired from 44 years in the U.S. Army where he fought against the Apaches and Sioux, served in the Spanish-American War, the Philippine Insurrection, and World War I (San Antonio Express Magazine [SAEM] , 11 January 1948). He paid $1,000 down and agreed to pay the remaining $5,000 over a five-year period (BCDR, 709:295). Colonel Coppock and his two sons, Edward Jr. and E. S., along with a Mexican laborer, are responsible for the structural concrete and stone foundations that are now on Comanche Hill. Between 1923 and the Colonel's death in 1948, they constructed the highly visible castle-like tower (Figure 4), a stone lodge, several outbuildings, a 2,500-gallon water tower, a Spanish style corral, picnic tables, a barbecue pit, a tennis court, and some smaller homes since destroyed by fire. The tower, modeled after "a similar structure erected by William the Conqueror at the site of the Battle of Hastings in the 11th century" (SAEM, 11 January 1948; San Antonio News, 14 November 1972) bears the colonel's initials and a date of 1928 above one of its openings. Unfortunately, Colonel Coppock died in 1948, before his U-shaped castle could be constructed over the foundation he laid.

After the colonel's death, the parcel was divided and changed hands several times. Finally, with the help of the Resolution Trust Company (San Antonio Express-News [SAEN] , 24 January 1993), the city of San Antonio acted to procure the colonel's property and other smaller parcels around it for a total of 96 acres. Soon after acquiring the land, the city began planning the park's development (SAEN, 3 June 1994; 7 May 1997).

Is the Lookout haunted?  Umm, maybe.

The Julia Yates Semmes Public Library was completed in 2005, at the corner of Judson and Nacogdoches Roads, in the southeast corner of the park.  The construction of the park was the inspiration for the formation of our group, the Friends of Comanche Lookout.

Ski Comanche Lookout?  You bet.  During the Snowpocalypse of 2021, some intrepid skiers actually skied down the slope overlooking the city, from the top.
