Ise Jingu Geku....one of the two main shrine sites in this sleepy little coastal city. The two shrines of Naiku and Geku are considered by many to be the first shrines in all of Japan.
One warning, they are not very photography friendly as I got in trouble for shooting one shot of some kind of holy building.
I ALWAYS respect "Do Not Photograph" signs and in my defence, there were no internationally recognizable signs around the building. Just one sign written in very uncommon kanji characters that even I didn't know how to read.
If you are in the area, stop by but I wouldn't make a special trip to go there.
