Castles near Alicante: from Santa Bárbara to the Almohad forts of the interior

Alicante province built more castles per square kilometre than almost anywhere else on the Mediterranean coast, because for centuries it was a frontier: first between Andalusi taifas, then between the Crown of Aragon and Castile, and later against Barbary raiders arriving by sea. This guide gathers the ones actually worth visiting or seeing up close, grouped by area, without padding the list with minor ruins that have no real access.

In the capital itself

Santa Bárbara Castle tops Mount Benacantil, 166 metres above the city, and its origins go back to the late 9th century under Muslim rule. It took its current name on 4 December 1248, the feast of Saint Barbara, when it was captured by Infante Alfonso of Castile, later Alfonso X. Jaime II rebuilt it from 1296 after it passed to the Crown of Aragon, and Carlos I ordered its definitive fortification in the early 16th century. Today it is a cultural centre with free entry to the grounds.

On another of the city's hills, Castell de Sant Ferran is far more recent: built between 1808 and 1812, during the war against Napoleon, to a design by military engineer Pablo Ordovás y Sastre. Through the 19th century it held a small garrison, and between 1906 and 1933 it served as a prison.

The southern coast, forts against piracy

The Santa Pola Castle-Fortress was built between 1554 and 1557 to a design by Italian engineer Juan Bautista Antonelli, part of a wider plan to defend this coast from Barbary raids. Its job was to protect the town from assaults launched out of Tabarca island; today it houses the Museo del Mar.

Further south, Guardamar Castle was founded by Alfonso X after the Christian conquest, on a hill above the Segura river. An earthquake in 1829 destroyed much of the fortification, and it now stands as a consolidated ruin, with active archaeological digs nearby, next to the Rábita Califal, the best-preserved 10th-11th century Islamic monastic complex in Spain.

In Orihuela, the Castillo-Alcazaba predates the Caliphate of Córdoba and stood as an active fortress until the War of Spanish Succession: an explosion in its powder store, triggered by lightning, destroyed most of the site in the early 18th century, and the 1829 earthquake finished the damage. Declared a historic ruin in 1931, it still stands as a ruin, and the town council is now seeking funding to consolidate it and open a proper visitor route.

The interior's Almohad group, in the Vinalopó valley

Villena, Biar, Petrer, Novelda and Xixona share more than proximity: their castles began as an Almohad defensive network in the 12th century, when this strip of land was the frontier between al-Andalus and the Christian kingdoms.

Castillo de la Atalaya in Villena is mentioned as early as 1172 and keeps Almohad ribbed vaults with crossing arches that have a parallel only at neighbouring Biar castle — no other military fortress in Spain has anything like them. It was declared a National Historic-Artistic Monument in 1931.

Biar Castle shares that same Almohad vault in its keep, a 19-metre, three-storey tower. Jaime I captured it in February 1245 after a six-month siege.

Petrer Castle, dating from the late 12th or early 13th century, changed hands repeatedly between Muslim and Christian rule after the 1244 Treaty of Almizra. The Bishopric of Orihuela handed it to the town council in 1968, and reconstruction work through the 1970s and early 1980s, reinforced again in 2010, leaves it in good condition today.

Castillo de La Mola in Novelda was built over an earlier Roman fort. Its most distinctive feature is the 15-by-17-metre triangular tower that Jaime II had built in the 14th century for his wife, Blanca de Anjou — no other tower like it survives in the military architecture of the period.

Torre Grossa Castle in Xixona fell to Jaime I in 1258. Its main tower, square in plan and 16 metres tall, guarded the approach to the compound from the north.

Andalusi ruins in the Marina Alta

Dénia Castle has topped the town since the 11th-12th centuries and was the seat of the Taifa of Dénia, founded in 1010 by the amirí Muyahid, who went on to annex the Balearic Islands in 1015 and whose taifa was the first to mint its own coinage, in 1011.

Inland, Castell d'Aixa, above Alcalalí and Xaló, was the Andalusi-era administrative head of thirteen alquerías scattered across the valley. Today it stands in near-total ruin, with a few stretches of wall still visible.

Near Pego, Castell d'Ambra is a late foundation, from the early 13th century, built as a refuge against the advancing troops of Jaime I. It was occupied for only a few decades: once King Pedro III founded the town of Pego in 1279, the castle was abandoned for good.

Guadalest, two castles and an earthquake

Castillo de San José in Guadalest is an 11th-century Muslim fortress built on top of the rock. The earthquake of 22 June 1644, followed by another that December, cracked the outcrop and brought down much of the compound; an explosion during the War of Spanish Succession in 1708 and a further earthquake in 1748 finished the damage. What visitors see today is largely that fragmented ruin, alongside the remains of its twin fortress, Castillo de la Alcozaiba.

Frequently asked questions

What is the oldest castle near Alicante?

Santa Bárbara Castle, with origins from the late 9th century under Muslim rule, though the hill it stands on holds remains going back to the Bronze Age.

Which inland castles share Almohad architecture?

Villena and Biar keep Almohad ribbed vaults with crossing arches found nowhere else in Spain's military architecture; Petrer, Novelda and Xixona belong to the same 12th-century defensive network.

Why is Guadalest's castle in ruins?

Earthquakes in 1644 and 1748, plus an explosion during the War of Spanish Succession in 1708, which together fragmented most of the San José compound.

Can you visit Orihuela Castle?

You can see it from the old town, but it is a consolidated ruin with no set visitor route yet; the council is seeking funding to restore it and open one.
