On a train trip to Italy from the UK in 2016, I saw some wonderful castles and churches from the train window. I think my favourite castles, were the ones perched up high on a hill top. This one I especially liked, as you can see the old stone castle walls surrounding the castle complex. I think we were going through Austria, or it could have been Italy 🙂
Update – After a bit of research, which I should have carried out before I posted, I found the castle. I also found another photo of the castle.
Reifenstein Castle (Castel Tasso) South Tyrol, Italy, there are apparently some wonderful frescoes inside the castle, so well worth a visit.
