I usually hate the words "simply must," in a blog post. But if you go to York you simply must visit York Minster Cathedral. Here are some things to do and see at this wonderful medieval gem that is my personal favorite of the cathedrals I've had an opportunity to visit.

When I was growing up I used to play in Alleyways -- but York has Snickelways, which are more than just alleys. Snickelways are narrow passages between buildings that locals use to take shortcutes to navigate the city faster. And York's still-standing walls are, perhaps, its largest Snickelway.

The Kirkmichael Trust Cemetery in the Scottish highlands has done some serious restoration work, bringing old medieval tombstones into a restored church building for preservation and display. The stones outside, as well as the small mausoleum, are also worth a visit if you like old cemeteries -- its just a bit off the main itinerary for your North Coast 500 road trip.
