The castle features a rare set of 'coracha' walls, which are defensive extensions designed to protect access to water sources during a siege.
The interior holds a collection of medieval torture instruments and historical weaponry from the reconquest period.
The fortification uses distinct 'tapial' construction, a technique of rammed earth and lime mortar characteristic of Andalusian military architecture.
The coat of arms of the House of Medina Sidonia is still visible above the main gatehouse.
The castle's foundation sits atop layers of Roman masonry, revealing the site's importance as a strategic military outpost for over 2,000 years.
Castle Niebla, also known as Castillo de los Guzmanes, is a well-preserved Almohad-era fortress located in the province of Huelva, Spain. The current structure primarily dates from the 15th century, built by the Dukes of Medina Sidonia upon earlier Roman and Visigothic foundations. It features a distinct Mudejar-style interior and a vast parade ground that connects to the town's defensive walls. Visitors can walk along the battlements and climb the keep to view the Tinto River valley. The castle historically served as the administrative center for the County of Niebla. Educational plaques are installed throughout the site to explain the various defensive architecture elements. The castle has undergone multiple reconstructions, most notably following the 1755 Lisbon earthquake. It is part of a larger fortified enclosure that spans nearly two kilometers of ancient walls.

Do not attempt to walk on the exterior section of the walls that are not marked as pedestrian-accessible paths.
