Historic sites...hmmm England? Visited prehistoric face paintings in France- done Stonehenge, iron age villages, Saxon burial mounds- they dot the landscape in the south, roman Bath( Aqua Sulus), amphitheatres in Lyon.. My daughter goes to Cambridge university which is 800 years old. The most historic site I remember tho is visiting Ephesus in Turkey - amazing! One more for me.
My MIL. Went to Venice last year to ride a gondola as part of her bucket list- she is 78 God Bless her!
