The castle was originally built during the 13th century on the foundations of an earlier Islamic fortification.
The 1829 earthquake, measuring 6.6 on the Richter scale, caused the collapse of most of the castle's structural integrity.
Archaeological digs at the site have uncovered ceramics dating to the Phoenician and Iberian civilizations.
The castle served as the primary defense for the town of Guardamar before the population moved to lower ground following the 1829 seismic event.
The location is part of the 'Castillos de la Vega Baja' defensive network that protected the southern Alicante border.
The Castle of Guardamar del Segura is a strategic fortification situated on a high hill overlooking the Segura River mouth and the Mediterranean coastline. Originating from the Moorish period, the site served as a vital defensive point against maritime incursions. It was heavily damaged during the 1829 Torrevieja earthquake, which leveled much of the original masonry. Today, the site consists primarily of archaeological remains and the reconstructed layout of the medieval fortress walls. Visitors can trace the perimeter of the former citadel, which includes sections of the Barbican and the inner wall. The elevation provides a panoramic vantage point of the surrounding salt flats and the Alfonso XIII Park. Excavations have revealed layers of occupation dating back to the Iberian era. The site is maintained as an open-air archaeological park.

Wear sturdy, closed-toe footwear as the path to the summit is gravelly and uneven.
Bring sun protection, as the site has minimal natural shade on the ridge.
Combine the visit with a walk through the adjacent Alfonso XIII forest park at the base of the hill.
Do not attempt to hike to the site in midday during July and August, as the exposed path offers no heat relief.
Respect the archaeological remains; do not climb on or deface the surviving stone wall sections.
