Ladyinspain we went to York for our honeymoon (obviously a long time ago). We were married in November so it was beautifully quiet outside of the normal tourist season and the evenings were cold, misty and full of fireworks and woodsmoke on Bonfire Night. Magical memories.
The Minster is incredible, the Shambles too but mostly I remember the narrow, cobbled streets, ancient city walls with beautiful arches in them, cosy pubs, twinkly little shops and cafes. I remember one pub had a glass floor so you could see the roman cellars below. Just 'being' in such an ancient feeling place for a few days was a real experience. When people say they went to New York on their honeymoon I always say, 'Oh, we went to Old York.'
