Imagine the consternation of the neighbors in what was then a somewhat rural community when the eccentric Henry Mercer began construction on his all concrete castle! Henry Mercer was an artist and entrepreneur. His unique tiles became desired all around the world. His castle is where he displayed the many different tile designs and mosaics. It is a wonder! I went for the 1st time in early 2012 and returned 2 more times within a couple of months. I plan to go back again and again. There is so much to see.
