This megalithic funerary monument is made up of a polygonal chamber measuring 3.5 meters in diameter, originally formed by seven granite pillars, four of which are broken. It reaches 3.10 meters in height, and the covering slab is preserved in situ. The reuse of the structure, at an unknown date, resulted in the filling of some gaps with dry stone. No corridor evidence was detected. In the surroundings there are some stony elements that could constitute vestiges of the tumulus.
The construction of Anta da Melriça is generically marked out between the mid-4th millennium and mid-3rd millennium BC. (Late Neolithic, Chalcolithic).
There are known documentary references to megalithic monuments in the Sever River basin since 1489, appearing in the Ordenanzas del Concejo de Valencia de Alcantara where they assume the function of territorial landmarks.

Sancho I made to the Order of the Temple in the rostrum indication of the Merliça.
