| To see Scotland's biggest broch involves a trip much further north to Shetland. |
| On the western end of the beach is a large, grassy mound with a shallow depression in the top. This is the site of a prehistoric fortification, or broch. |
| The spectacular brochs were built, most impressively the nearly complete broch at Mousa on Shetland. |
| Then we climbed into a nearby 2,000-year-old broch, a multistory stone fortress with double wails and one of best preserved from the pre-Viking era. |
| The remains of one broch stand on a promontory at Invernaver, overlooking the mouth of the river. |
| The early Norse settlers built their farmhouse close to the ruins of the old broch, which doubtless served as a handy source of good stone. |
