Sierra Martilla

Sierra Martilla is a megalithic archaeological complex in the municipality of Loja, in the province of Granada, Andalusia. Standing on a limestone-sandstone plateau roughly 800 metres above sea level, it holds a settlement and necropolis that span several millennia of human presence, from the late Neolithic through to the Arab period.

Where is Sierra Martilla located?

The site sits on the right bank of the Genil river, close to the small settlement of Ventorros de San José, about 4.5 km away. A footpath leads there toward Las Rozuelas, near the road connecting Loja with Priego de Córdoba. The plateau rises noticeably above the surrounding rock formations, which made it both a natural lookout point and a favoured place to settle.

What can visitors see at the site?

The core of the complex is a megalithic necropolis spread across two clusters on the south-eastern slope of the hill. About ten dolmens have been identified, each with one or several burial chambers, some partly carved directly into the rock. The tombs show a striking range of construction types: chamber-and-corridor structures, tombs cut into or adapting natural caves, combinations of artificial caves with megalithic elements, simple pits dug horizontally into the ground, and double or triple chambers. Finding so many burial typologies concentrated in one place is unusual and gives the site real weight for research into Iberian prehistory.

How far back does the site's history go?

Sierra Martilla's timeline runs through several distinct phases. The earliest megalithic burials date to the late Neolithic, in the 4th millennium BC, with a further phase of dolmen-building during the Copper Age, in the 3rd millennium BC. The settlement remained in use later during the Iberian and Roman (republican) periods, and Visigothic burials have also been documented within the complex. The final chapter belongs to the Arab period, which left behind a watchtower (atalaya) crowning the hilltop — part of a defensive and observation network overseeing the Genil valley.

How do you visit Sierra Martilla?

The site is an open-air archaeological area reached via a marked footpath from Ventorros de San José. Before setting out, it's worth stopping at the Centro de Interpretación Histórico de Loja, on Plaza de la Constitución in the town centre, which provides route information and materials on the complex, including an up-to-date guide to Sierra Martilla. Visiting independently calls for sturdy footwear, since the ground is rocky and the site lacks the amenities of a developed tourist park — this remains primarily a research site rather than a landscaped attraction.
