Here are seven unique, strange and wonderful must-see destinations.

2. Church of St Mary the Virgin, Burgh St Peter

After the original tower had fallen down, a new one said to be based on the Ziggurat temples of Mesopotamia in Iraq, was built, and made the church a must-see sight.

3. The Blickling Mausoleum

The Blickling Mausoleum was commissioned by Lady Caroline Suffield in 1793.
