Talamanca de Jarama is a small Spanish town, just 50 miles north of Madrid. Today it may be fairly quiet, but back in the medieval period, it was a strategic point in the battles between Visigoths, Muslims and Christians.
The discovery, which has been called the most important in the region this year, was made when restoration work was being carried out on a wall built by Catholic monks in the 18th century to protect their monastery’s farm.
The restorers soon realised that its foundations were built on top of another, much older wall which had remained hidden underground.
Talamanca’s first defensive wall was built in AD 860, on the order of Muhammad I, Emir of Cordoba. The second arrived in the 10th century, and was bigger and enclosed an even larger area. Later, in the 13th and 14th centuries, the Christians conquered the enclave and built their own wall – the one that has now been found.
Archaeologists were surprised to discover that its length was defended with seven turrets, each placed exactly 21m from the next, which survived up to 2m high in places.
As if the wall didn’t already carry enough history, four pieces of richly carved stone were spotted in among the wall’s construction, from the rubble of a Visigothic building whose rubble was re-used in the wall’s later construction. The Visigoths had occupied the area before the 9th century.
The wall is now being conserved and restored, and will eventually become part of an open air museum.
