Burra Firth, in the north of Unst, is flanked on both sides by magnificent cliffs, including the Noup of Unst, the hill of Saxavord (934 ft.), the Gord and Herma Ness.
The Eure, which at this point divides into three branches, is crossed by several bridges, some of them ancient, and is fringed in places by remains of the old fortifications, of which the Porte Guillaume (14th century), a gateway flanked by towers, is the most complete specimen.
Ashwood Dale, Chee Dale, Millersdale, Monsal Dale and the valley at Matlock are all flanked by abrupt sides of this rock.
It is surrounded by old walls, flanked with towers, and has a considerable number of ancient buildings, among which are the fine church of the Holy Cross; St John's church, which dates from the time of the Hohenstaufen; and, situated on a height near the town, partly hewn out of the rock, the pilgrimage church of the Saviour.
The sacred road from Epidaurus, which is flanked by tombs, approaches the precinct through a gateway or propylaea.
