The Oldest Buildings in the World

4. Knap of Howar (3700 BC), Scotland

This structure in northwestern Europe is a stone house dating back to 3700 BC. Knap of Howar is the oldest and best-preserved example of its kind.

Located on Papa Island in Scotland, the house also draws attention with its seafront location. The view where stone walls and waves meet on the same stage is definitely worth watching.

Archaeological studies show that in the past, fishing was practiced here, fires were lit, small cattle were kept, and provisions were stored in large rooms.
