8 Scara Brae, Orkney Island, Scotland

This is regarded as one of Europe's best monuments. It is an UNESCO world heritage site and dates back to the Neolithic Period of around 3200 B.C. This is about 650 years older that the pyramids in Egypt. These homes would have had a turf roof over them but are now open to the elements and visitors alike. On a side note, the Orkney Island is home to the biggest cows we have ever seen.
