My French Retreat: The foundation was built on top of the escape tunnels of the old original Chateau as early 1160 and now the sealed tunnel / dungeons below the house. There maybe a connection to the other garage across the street as the cement slab was built on top of a gravel pit to fill up another tunnel connecting to the house. It was common during the olden days. Also the proximity of the house from the church may suggest that it was a part of the original ancient village around the church.
Home sweet home: While there is nothing fantasy-themed about the outside of his house, underneath is perhaps the finest example of a man cave ever created
There is even an alcove for Tyler's one-year-old boy - who he plans to introduce to the Elder Scrolls series once he is old enough to play.
