As years faded into decades and decades to centuries, many of the ancient remains of Guardamar del Segura have been lost by the passage of time, however not all are gone and forgotten.
One important site that remains and can be seen looming over the town is the Guardamar Castle. Dating back to between the 9th and 10th centuries Guardamar Castle is unique to the west and has been declared a site of cultural interest. It was built by the Arabs to guard the land. Much of it has been destroyed, although it is still worth taking a trip to the castle for the exceptional views and photo opportunities.
