Son Mercer de Baix naviform settlement

The Son Mercer de Baix settlement, inhabited between the Early Bronze Age (1400 B.C.) and the Talayotic era (1000 B.C.), is one of the best-known archaeological sites on Minorca.
It consists of several habitational chambered cairns (navetas), strategically located overlooking En Fideu ravine (Ferreries).
One of these navetas is the Es Moro cave, with an apse-shaped floor plan and with part of its roof extant, supported by three stone columns characterised by their small base, widening towards the ceiling.
The remains found among the structures in the settlement may indicate a bronze foundry or workshop, suggesting that the settlement may have specialised in working this metal.


Detailed description

Son Mercer de Baix is a settlement of naveta dwellings. Four naveta units have been identified, along with another two square-shaped spaces. It is located in a highly strategic setting on En Fideu ravine, which forms as a boundary, a source of sustenance and a channel of communication with the sea.

Naveta 1: Known as Es Moro cave, this is an elongated apse-shaped building with a very regular exterior wall of well shaped stones. Part of the roof is preserved, with horizontal slabs supported on three polylithic columns (small base stones but widening towards the ceiling) set along its length, and on its interior walls. It abuts another unexcavated unit.
Dimensions: length 17.30 m; width 7.20 m

Naveta 2: Semi-circular apse floor plan, straight walls and a bench to the left of the entrance. Oriented eastwards. Excavated in 1962 by Mª Luisa Serra.?Dimensions: length 6 m

Naveta 3: With oval floor plan, located beside Naveta 2 but with opposite orientation. At an indeterminate time, the entrance was blocked and a side entrance created.
Dimensions: length 9.80 m; width 6.30 m

Naveta 4: With elongated apsidal floor plan and concave façade, it has a small transversal wall beside the door.
Dimensions: length 18 m; width 7.60 m

The rectangular spaces referred to adjoin Naveta 4 and also have double-faced walls. During its excavation, bronze ingots, slag and several melting pots were found, indicating the presence of a small metallurgical bronze workshop.

Archaeological interventions

There have been several digs, the first in 1962, when archaeologist María Lluïsa Serra excavated Naveta 2. Navetas 3 and 4 were excavated between 1977 and 1982. In subsequent years there was prospecting in the area around the settlement. Finally in 2002 the exterior of the naveta in the Es Moro cave was excavated and the entrance column restored.
