On June 2, 2018, those who were then the mayor of Es Castell, Lluís Camps, and the General Commander of the Balearic Islands, Juan Cifuentes, inaugurated the new access from inside the Military Museum to the old underground tunnels of the Civil War that are taking place through the basement of Plaça Esplanada, as part of the Armed Forces Day celebration.
This initiative counted with the collaboration of Es Castell volunteers and financial contributions from the town’s City Council, the Balearic Government, the Insular Council and the Menorca Military Consortium.
It took 3 years of bureaucratic procedures and 8 months of works, in charge of the company M. Polo, to recover half of the 200-meter-long tunnels, which are located 7 meters deep. In addition, very dim lighting was installed and loudspeakers that reproduce the sound of the bombs and sirens that warned the population so that they could take refuge.
The opening of the tunnels followed the raising of the flag by a section of the Palma 47 Infantry Regiment and preceded the first historical recreation of the 2018 tourist season of the Treaty of Amiens, with the lowering of the English flag of Unity and hoisting of the Spanish of the Soria Regiment.
In addition, a parade was also held by the Military Music Unit of the General Command of the Balearic Islands, which performed several popular pieces.
