Set on the eastern edge of Birgu's fortifications, the Post of Castile is one of the best places to visit in Birgu for travellers wanting to trace the city's most dramatic moments of resistance. Built in 1553 by the Spanish Knights of the Langue of Castille, it commanded views over Kalkara, Santa Margherita Heights, and the approaches to the Grand Harbour. Its elevated defensive position made it a key stronghold in the city's outer fortifications.

This site is a great place to visit on a walking tour of Birgu, not only for its architectural presence but for the extraordinary courage displayed here during the Great Siege of 1565. The walls, tunnels, and hornwork surrounding the bastion still evoke the ferocity of Malta's most defining conflict, making it one of the most atmospheric stops for anyone exploring the Three Cities.

History and Significance of the Post of Castile

When the Post of Castile was constructed in 1553, Malta was still preparing for the looming Ottoman threat. The Langue of Castille built and manned this bastion to safeguard Birgu from attacks launched across the peninsula. Positioned to cover strategic approaches, its elevated placement allowed defenders to monitor incoming forces long before they reached the city walls.

Its true test came during the Great Siege of 1565. Subjected to heavy bombardment from multiple angles, the bastion absorbed some of the fiercest artillery fire of the campaign. A direct hit eventually tore through the wall, creating a breach that allowed Ottoman forces to surge forward. As panic spread, Grand Master Jean Parisot de Valette personally rallied the defenders, leading a counter-attack that pushed the Ottomans back through the gap. His intervention saved the city from collapse but left him wounded. In memory of this dramatic moment, the damaged section of wall became known as Il-Prexxa, “the breach,” a permanent reminder of Birgu’s near fall and extraordinary recovery.

The bastion continued to play a crucial defensive role for centuries. British engineers later adapted parts of the site, while World War II saw its tunnels and storage rooms reused as air-raid shelters, protecting civilians during heavy bombing raids across the Grand Harbour.

Things to See and Do in the Post of Castile

A visit to the Post of Castile offers a deep dive into early modern military design. The bastion was originally enclosed by a hornwork — an additional fortified layer designed to slow attackers and absorb artillery fire. Visitors can still see parts of this outer structure, along with the protective ditch that once surrounded it.

Inside the bastion, interconnected tunnels, storage areas, and ammunition rooms reveal how defenders moved unseen during sieges. The presence of caponiers — enclosed passageways that allowed safe firing across the ditch — highlights the tactical sophistication of the Knights' engineers. Standing atop the bastion offers wide panoramic views over Kalkara Creek, the Grand Harbour, and Fort St. Angelo, giving visitors a sense of just how important this vantage point was in defending Birgu.

Interpretive signage and occasional heritage events help bring the battlements to life. Even without formal exhibitions, the atmosphere alone makes the Post of Castile a powerful stop for history enthusiasts.
