You get to this church from Lions Gate. If I'm remembering correctly, you just continue down the street after entering the city. The Palm Sunday procession we went to ended here, and I think I went in the church one other time. The Ecce Homo Church is in the convent.
But the main reason I always noticed this spot is the arch over the street outside. Since we often used Lion's Gate, we'd walk under this arch and I'd always think about this church and the story in the Bible about it.
