Derry Walls — Columba's Exile Secret

Your quest begins at the Grianán of Aileach, an ancient circular fortress built around 1700 BC, a ceremonial site of the Kingdom of Ailech. This legendary palace of the O'Neill's, located 7 km from central Derry, offers panoramic views of the Inishowen Peninsula and Lough Foyle. Restored in 1976, this structure with an inner diameter of 17.3 m and a 4.5 m thick wall witnessed the earliest rituals and decisions that shaped Ulster, long before Saint Colmcille's arrival. Here, legends intertwine with real history, laying the foundations for your exploration of the Northern Ireland Heritage Trail.

Continue to St Columba's Church, known as Long Tower, Derry's first post-penal Catholic church, built between 1784 and 1786. Its neoclassical architecture by Charles Lanyon, featuring a dome inspired by Rome's Pantheon, is dedicated to Saint Colmcille. Stained-glass windows commemorating the 1689 Siege of Derry recall the community's resilience. This site, erected centuries after Saint Colmcille's exile, illustrates the persistence of his spiritual legacy in the city of Derry, confirming his role as a central figure in the city's history.

The path then leads you to the Derry Walls, specifically the Magazine Gate, the western gate of the walls built between 1613 and 1618. This gate housed the powder magazine during the 1689 siege, where an explosion on April 18, 1689, killed six Jacobite attackers. Remains of the powder magazine are still visible in the basement of this gate, one of the most photographed of the Derry Walls. The Derry Walls, Ireland's longest complete urban walls (1.6 km), withstood 105 days of siege in 1689, a major event that marked the history of Derry and Ulster.

Walk through Guildhall Square, dominated by the Guildhall, a Victorian Gothic building constructed in 1890 and rebuilt after a fire in 1912. Its 55 m long facade is adorned with 14 Tiffany stained-glass windows illustrating Derry's history. The seat of the Derry City Council, this location also saw the signing of the Good Friday Agreement in 1998, a key event for peace in Northern Ireland. This stop allows you to understand how the city of Derry has reinvented itself and built its future, while honoring its tumultuous past.

Conclude your journey at St Columb's Cathedral, consecrated in 1633, the oldest cathedral in Northern Ireland still in use. Its 43 m bell tower is said, according to 12th-century legend, to contain stones from Solomon's Temple brought back by crusaders. The cathedral houses Bishop William Bedell's Bible (1629), the oldest printed text in Irish. Canon Jeremy Taylor served as a canon there during the Siege of Derry. This monument, designated a national monument since 1993, represents the culmination of Derry's religious and historical heritage, completing your exploration of the secret of Columba's exile and the deep identity of this Ulster city.
