The dolmen of El Tesoro (Basque: El Tesoro trikuharria) is a megalithic tomb in the territory of Morales de Rey, in the province of Zamora, Spain. It is dated to 3500 to 3000 BCE, and it takes its name from 18 Roman bronze coins found there.
It was very badly damaged by intensive farming, but excavation showed that it is a passage grave.

The dolmen had been badly damaged by the extensive agricultural cultivation of the surrounding land. Excavation uncovered a passage running to the south-east, which made it easy to classify the monument as a passage grave. There was no mound: the site had been subject to several earth movements, and the mound had disappeared completely.

Few archaeological materials were recovered. They were objects left beside the dead as grave goods, namely several flint tools, Neolithic pottery and fragments of some ornaments.

Tradition and region
About this kind of monument
Dolmens of Andalusia, Extremadura and Galicia
Spain has a great many megalithic tombs, and the Atlas's Spanish dolmens run from Andalusia in the south to Galicia in the north-west. The finest are at Antequera in Andalusia, where the Dolmen of Menga, dated to about 3750 to 3650 BCE, is among the largest ancient megalithic structures in Europe. It is 27.5 metres long, 6 metres wide and 3.5 metres high, built with thirty-two megaliths, the largest weighing about 180 tonnes. After the chamber was finished it was covered with soil and built up into the hill seen today; when it was opened in the nineteenth century archaeologists found the skeletons of several hundred people. The Dolmen of Viera stands 70 metres away, and the tholos of El Romeral lies about 4 kilometres off; the three were inscribed as the Antequera Dolmens Site, a UNESCO World Heritage Site, in 2016.
In the south-west, the Dolmen de Soto at Trigueros in Huelva province is a Neolithic tomb estimated to date between 3000 and 2500 BCE, one of about 200 Neolithic burial sites in the province. It was found in 1922 when its owner, Armando de Soto Morillas, wanted to build a house; the German archaeologist Hugo Obermaier found eight bodies in a fetal position with artefacts, and its engraved and painted uprights have been studied more recently.
In Galicia and Portugal a dolmen is an anta, and in Catalan-speaking areas dolmens have folk names such as cova (cave), caixa (crate or coffin), taula (table) and arca (chest). These names are tradition: they record what people made of the monuments, not what they were built for.
When visiting Menga, look at the great capstones from inside the corridor, and at the way the mound was built up over the chamber.
