The Church of the Holy Sepulchre is the holiest site in Jerusalem, and of all Christianity. Located within the Church is the Tomb of Christ, with steps leading up to Golgotha (Calvary) where Christ was crucified. The church was built around the tomb in 330AD by Emperor Constantine. Pilgrims can see the place where Jesus' body was laid, as well as a piece of the stone that was rolled away.
Inside St. Mark's Basilica, Venice, Italy. We squeaked in the tourist line right before the cut off time, and we were in there with very few people, at sunset, nothing but candles and some dusty sun rays. Unbelievable sacred and beautiful place! Those images covering the walls are made out of tiny gold mosaic tiles. Millions of them.
