I love the Church of the Holy Sepulchre in Jerusalem because I believe its the authentic site of Our Lord's Crucifixion and Burial; also because the Byzantine architecture of late antiquity soars - the dome pictured appears to float, which is no mean feat and right ethereal. You'll meet monks there, begging for money; give it to them, far better value than various other taxes.
I know it sounds 'sexist' but the women of the parish(s) don't want to pay these anymore and talk angrily about 'secession'. They're very fierce and radical.
Keep the Holy Places safe,
