In the second half of the 16th century, where the park is today, there was a hermitage dedicated to San Sebastián. Later, next to it, the Convent of San Agustín was founded, the hermitage becoming the church of that convent, where the patron saint of the town, San Sebastián, was venerated.

On October 9, 1680, an earthquake occurred that caused the collapse of the Main Chapel of the Church of San Sebastián. After the earthquake, the Chapel is rebuilt and, over time, what was the Convent collapsed in 1887.

Thus, this beautiful Park was built on the remains of the Convent of the Augustinians (16th century), taking its name from there, and today it is adorned by gardens and a set of leafy and centennial Estoraques. In the center of it is an obelisk, in homage to those who died in the Spanish Civil War.
