The archaeological evaluation carried out in the first of the Impossible Works (OBIS) between San José and San Ramón, known as Barreal-Castella Connector, discovered a pre-Columbian funerary zone and allowed the recovery of four tombs, multiple boulders, two clay pots and a gold earring, reported the Ruta Uno Trust.
During the initial earthworks of this work – started at the end of May and which is already 54% complete – a finding was presented, which activated the protocols established in Law No. 6703 “Law on National Archaeological Heritage” .
From that moment, the National Museum of Costa Rica took control of two sites and requested the Trust to hire professionals in archeology to develop the corresponding evaluations. The preliminary results of the contracted study are as follows:
Zone 1: connection area of the new works with Route No. 1. Initially it was believed that it consisted of a pre-Columbian road built with stones or pebbles; However, the archaeological study revealed that it is a more modern road, built by the former owner of that land to facilitate the transportation of the coffee collection.
Zone 2: current bus bay in the direction of San José – Alajuela, at the height of the Castella school. The archaeological evaluation allowed the discovery of multiple boulders, four tombs, two clay pots and a gold earring in the shape of a bird. For the study, a sampling was carried out with wells separated by 5 meters and the result of these excavations led to the discovery of a funeral area. All elements are in their final analysis stage.
Magdalena León, an archaeologist hired by the Trust for the evaluation, commented that the site where the works are carried out is multicomponent, that is, it had occupations during several periods, which explains why pre-Columbian elements of different phases and post-Columbian have been found.
“That is why the excavation that has been carried out has been delicate and meticulous in order to be able to distinguish well those periods, since it is a site of more or less 100 hectares of extension”, explained the expert.
During the last days, the Trust informed the National Museum about the preliminary results of the archaeological evaluation, where it is highlighted that none of the findings compromise the design of the work or the archaeological structures found, since these have been duly recovered by the specialist hired by the Ruta Uno Trust.
As stated by Alejandro Araya, environmental supervisor of the Trust, “the construction company will be able to resume construction work once the National Archaeological Commission lifts the temporary suspension of the sites under study, officially authorizing the continuation of the works in said land ”.
In fact, authorities from the National Museum authorized the resumption of work on the site of zone 1, pending that of zone 2.
