The Fortress
Nuremburg has a relatively large fortified area, including several buildings and a 40m deep well. It is set in the traditional manner on the top of a hill and has an enormous moat on the more appproachable side. The former stables are now used as a youth hostel, in which we didn't stay, as Bavaria has very strict laws, which mean that only under 27 yr olds can stay there.
The view from the fortress is magnificent, especially at sunrise.
In case you're wondering, sunrise was around 9am, my habits haven't changed that much ;-)
