For some reason, Lonely Planet fails to mention the Roman fort at Saalburg at all. This is a failing on its part. The fort at Saalburg is fascinating and enjoyable. Just getting to the fort, unless you have a car, is a bit of a challenge, but it’s a very enjoyable one. You can get the train from Frankfurt to Saalburg (Taunus) – otherwise known as Saalburg/Lochmuehle after the theme park nearby – and then walk around 3km through pine forest to get there. On the way, there are a couple of remains of Roman lookout towers. It is all meticulously signposted, and there is a bridge over the main road when you get there. All in all, it’s an enjoyable little trek.
When I was there, this morning, it had an event on at which various people dressed in Roman garb demonstrated and discussed Roman life. I didn’t understand much, as my German isn’t up to it, but it is apparently quite a frequent thing, especially in summer, and it was very impressive.
There are some ruins, several reconstructed buildings and a full fort wall running round the site, but also in some of the buildings some little museums with some impressive artefacts including wooden implements and shield bosses.
