One of my favorite buildings in vanished Los Angeles is the 1888 City Hall. It was located on the east side of Broadway, roughly mid-way between Second and Third Streets.

I can't recall where I read this, but supposedly, the City Hall's bell tower was the tallest structure in Los Angeles County at the time of its completion.
The
Bradbury Building can also be seen in the background at the corner of Broadway and Third, where it stands to this day.
