Mysterious tower atop San Antonio's fourth highest peak to get facelift

"Comanche Lookout Park, a 96-acre oasis in the urban sprawl of the city's Northeast Side off of Nacogdoches Road, has a peak with an elevation of 1,340 feet. Throughout history, the site has provided a location for commerce as well as a site where raids were performed on Spanish and Mexican mule trains and pioneers. "

There is also a four-story stone tower that was built in 1923. Retired Army Colonel Edward H. Coppock purchased the land that would eventually be the park in 1923 and planned to build a castle-like house, but the project was abandoned after he died in 1948, according to the city's parks and recreation website. It's remained there since.

so... that 'mysterious' was a lie.
