Fr. V shared this link to a site where you can see a 360-degree view of the the Church of the Holy Sepulchre. Good stuff. Unfortunately, it doesn't look like there are any vertical views, so you don't get to see the beautiful Christ Pantocrator over the Greek Orthodox chapel. I've included a shot of it in this post, and you can view my other photos of Israel from here.
UPDATE: My mistake! If you click the Details tag on the right side, you can get directional controls to view the ceiling. I'm still searching to find images of Calvary. You can see the stairs up to the site of crucifixion, but so far, no Calvary.
