The Agua Caliente Hotel and casino must have been a beautiful place back in the 1930's. Sadly, just about all of it has been torn down and lost to time. One piece that the city of Tijuana has tried to restore is the pool and facade around it. It appears the arch with the colorful tile was all that remained around the pool and then the other building fronts were redone to loosely create the surroundings. Of course all the buildings are no longer there but, it's a pretty nice redo. The first photo is of an old 1930 post card. The rest were grabbed off of Google maps.
