City boundary marker

If you fancy a stop off on your walk here you can see dug out caves behind the museum and visit the World War II air raid shelter or take a look around a Victorian home.

As you walk through these grounds and get close to Castle Boulevard take a look behind you at the steep cliffs. You'll notice a number of modern pillars holding up the rocks. This was the result of a major landslip on Christmas Day in 2000.

More evidence of caves around Nottingham castle

In the grounds there's a hornbeam, a tree grown in Epping forest to supply local bakeries with wood. It's not common to Nottingham.

Now we're back onto the main road (Castle Boulevard). Cross over the road and you'll be in front of the Gala building. This is actually a listed property. It used to be known as the Viyella building and you're right, it's not very old, but is one of Nottingham's modern listed buildings.

On the opposite side of the road is the Castle Works. This used to be the city's waterworks. If you ever bought a tap for your kitchen or bathroom you had to take it here and have it stamped. It was a sign that it met the standards set by the company.

Carry on along Castle Boulevard towards the Nottingham Evening Post offices.
