After 7.5 years of mapping about 500 Forgotten French LA sites, I think I have a pretty good idea of what was located where.
Most of what we had has been lost over the years. As a result, most people have NO idea about the city's French history. Out of sight, out of mind. But we did not, in fact, vanish "without a trace" as another historian has claimed. There's plenty of evidence if you know where to look.
Frenchtown is long gone - lost to redevelopment by about 1940 (except for the original Taix restaurant, which remained until eminent domain took it away in 1964). The El Aliso/Sainsevain Brothers vineyard was buried by the Civic Center, Little Tokyo, and the north end of the Arts District. The 101 Freeway wiped out the Jennette Block and half of the Garnier Building. Ducommun Yard is now a bus parking lot. Many, many properties became parking lots.
What we do still have, though, are French street names.
It's unusual for street names to change. We did lose a few, but we still have most of our French street names.
Let's take a ride.
Lost to renaming:
Dupuy Street in Temple City ("too hard to pronounce", supposedly,). It became Primrose Avenue, but there is still a short residential cul-de-sac called Dupuy Circle.
Sentous Street downtown. The Sentous tract was redeveloped into (what else...) a parking lot for the Convention Center, and Sentous Street was renamed LA Live Way.
Lost to redevelopment:
Leonis Street downtown - not the same as the Leonis Street in Commerce or Leonis Boulevard in Vernon. Miguel Leonis named the street during his lifetime. Commerce and Vernon would not exist for many years.
