Absolutely, the London Edinburgh train stops at the ancient, castled cities of York and Durham before making its way up the Northumberland coastline.Ah interesting.
People say train up to Scotland is scenic in many parts, the coastal areas. Northumberland must be one of those areas.
An often missed beauty is the city of Durham with its working castle and cathedral, side by side and high on a hill surrounded on 3 sides by the river Wear. In the Cathedral, above one of the arched doorways is the ancient coat of arms of the Washington family (yes, President George Washington's ancestors from the twelfth century). The coat of arms of 3 red stars over stripes is said to have inspired the Stars and Stripes flag of the USA.
Those who have seen Harry Potter movies will have seen parts of Durham Cathedral as well as Alnwick Castle on the Northumberland coast. (Hogwarts)
