Were the stones in this wall at Temple and Spring once part of the retaining wall around the north and east perimeter of the old County Court House? They sure look familiar to me!
There's precedent for the re-use of these stones. When Spring Street was realigned in the 1920s, the stones were saved and used to rebuild the wall. (You can see them piled up on the lawn there above the new cut.)
Spring and Temple, late 1930s.
Could some of the stones have been re-used again for the wall in front of the Criminal Justice Center? Like I said, they look awfully similar!
This is an historically important question, because if the answer is yes, these stones would be the oldest remaining remnants of Los Angeles's Civic Center...
