Jim Bishop is a very interesting man with an odd obsession.
He has spent the last 42 years building a huge castle in the mountains of central Colorado.
Without any help at all, he has gathered and placed over 1000 tons of rock, stone, and iron.
The tallest tower is 160 feet high.
Jim has lots of one-liners about why he has been doing this.
"I always wanted a castle. Every man wants a castle."
"Did it all myself, don't want any help."
"It's a monument to hardworking people."
"I want to live as long as I can and keep building that castle bigger and bigger and bigger."
Jim has been working on the castle since 1969, and has no plans of stopping.
