From the reviews

An experience for sure! Junior is fascinating and will lead you on a tour around the castle he built. If you drive up, he can appear out of no where so just wait around the front yard. This is his life’s work and everything he has done is for God. You may question some stories but everything is very fascinating.

Mike "TaleRider" Swain, a good Brother of mine, rode in from Oklahoma to join in the LibertyCon convention fun. Post Con, we went on a round about little adventure.

★★★★★ — Scott, Jun 2025

This is a religious castle, but it does give off super spooky vibes. Alot of the negative reviews on this place is mainly people who never gave it a chance. Very detailed throughout, and super cool structure. It is located next to some housing yes, but the neighbors was super friendly and welcoming to us.

★★★★★ — Ricky, Jul 2025

Built, but unfinished, by a man who is inspired to tell the world about Jesus. He believes there is very little time left for the world. He hasn't been able to work, because of his health for quite a while.
