La segunda línea de defensa consistía de una muralla que corría desde el océano Atlántico en el norte hasta los manglares del caño de San Antonio al sur de la Isleta de San Juan, un tramo de aproximadamente 430 metros. Se construyó en varias etapas durante el último cuarto del siglo XVIII como protección adicional por si el enemigo lograba rebasar la primera línea, euq estaba en el extremo este de la Isleta. Además, protegía contra desembarcos de tropas enemigas en naves pequeñas en la playa al norte. Al extremo sur de esta línea (cerca de los manglares del caño de San Antonio, los cuales ya no existen pues el área fue rellenada), se construyó un bastión con foso seco y murallas con troneras para emplazar cañones, que luego se llamó Bastión Isábel II, en honor de la reina de España.

Dicha segunda línea restringía el crecimiento urbano de Puerta de Tierra, lo que eventualmente contribuyó a la casi total desapraición de la línea. De la misma sólo quedan las ruinas del bastión, sin el foso, y unos fragmentos de muralla en la costa norte de la Isleta, observables desde este punto. Las ruinas del bastión de Isabel II se pueden

The second line of defense consisted of a wall that ran from the Atlantic Ocean on the north to the mangroves of the San Antonio Channel on the south of the San Juan Islet, a distance of approximately 1,400 feet. It was built in several stages in the last quarter of the 18th Century, as additional protection in case enemy troops breached the first line of defense, which lay on the eastern end of the Islet. It also provided protection against the landing of enemy troops in small boats along the northern beach of the Islet. On the southern point of this line (close to the San Antonio Channel mangroves, that no longer exist because the area is now landfill), there was a bastion with a dry moat and walls with cannon embrasures, later named it Isabella II, after the queen of Spain.

This second line restricted the urban growth of Puerta de Tierra, which eventually contributed to the almost disappearance of the line. Its only remains are the ruins of the bastion, without the moat, and some wall fragments on the north coast of the Islet, which are visible from this point. The ruins of the Isabella II Bastion can be seen on the corner of Constitution Avenue and San Agustín Street.
