I had travelled from Antwerp to Schengen in Luxembourg. I thought I might see, among other things, The Princesse Marie - Astrid, the boat that the Schengen Agreement was signed on. The boat is no longer there though, which I hadn’t thought to research. It’s in Germany now, in Regensburg, and sails as the MS Regensburg on the River Danube. It takes people on day trips to The Walhalla Memorial which is a short journey from the town. I found out The Walhalla Memorial is a hall of fame that houses statues, or busts, of significant figures from German history. When I left Schengen that day I saw a car parked by the road with a picture painted on its side. It didn’t occur to me until later that the picture is a scene from Norse mythology in which a Viking ship sails past Walhalla, the great hall of Odin, where warriors who have died in battle gather in heavenly revellry. The car, like I said, had Russian license plates.
