El Tossal, also known as Monte Tossal, is a promontory with a height of 87 meters above sea level, where the San Fernando Castle is located. El Tossal is embraced by the Alicante neighborhoods of San Blas, Mercado and Campoamor, representing an enclave of significant environmental value for the City.

In 1911, the Alicante doctor Antonio Rico Cabot, being a councilor, proposed to the City Council to acquire the mountain of San Fernando Castle, a barren and desolate promontory, to reforest it with pines and turn it into a green lung and recreational area for the population. Dr. Rico recommended that Alicante should not invest anything, but that the councilors and the mayor should provide the capital due to the lack of funds in the municipal coffers. The project would go ahead, with the City receiving four-fifths of the total land and later the remaining fifth, with a total investment of 50,000 pesetas at that time. ‘Its forest repopulation would cost the Town Hall nothing as it was undertaken by the Tree Protection Society.’
