Sweet smoking Judas, that's a solid pile. Two additions - the transmitting tower on high, which was also used for human sacrifice in the worst years of the Depression, and the addition on the left, which was done in a slightly different color stone. (The older stone was apparently cured in butter, and they couldn't match the hue.) The addition has the unfortunate effect of diminishing the building's ascent - makes it waddle instead of soar.
