The defensive walls of Albarracín are the town's most striking feature from a distance — a line of pale stone that climbs the steep ridge above the houses, crowned with square towers at intervals and dropping sheer down the gorge of the Guadalaviar on the far side. The walls are mostly Moorish in origin (11th century) with Christian additions, and large sections can be walked.
The standard climb is from the Plaza Mayor up to the Torre del Andador, the watch tower at the highest point of the circuit. The path is steep and stony but rewards you with one of the great medieval views in Spain — the russet rooftops of the old town below, the river coiling around the rock, and the pine-covered Sierra de Albarracín stretching away.
