I was staying opposite the Church of St Ursula, woken daily by the clang of bells, though the church was open there is an iron screen at the back to stop people wandering around. Inside the Church there is chapel, which I didn't get into, containing the relics of St Ursula the Virgin Martyr and her 1100 companions.
Such is the wonder of modern technology that what one can't see in reality flickr provides.
I was very impressed with the fascinating collection of relics I saw in Germany: the Magi, the belts of Our Lord and his Blessed Mother, I think I encountered Our Lord's lioncloth somewhere, and then there was St Peter's staff in the Cathedral, which actually does have a Roman knob on it. It is fascinating insight into Medieval spirituality.
