Nestled behind lofty city walls, Londonderry is a destination of culture, which boasts an increasingly envied reputation. This Northern Irish city is still riding on the momentum of a fantastic 2013, when it was named as UK City of Culture, and singled out as one of Lonely Planet's top 5 destinations to visit. The wonderfully preserved city walls are perhaps Londonderry's most treasured charm, and they encircle 1,450 years of history, and are over 400 years old. The walls came to the fore of the city's history during the Siege of Derry, back in 1688 - when King James's forces attacked, causing mass starvation and suffering over 105 days of stalemate. It takes approximately an hour to wander the entire circuit of the walls, and see their seven gates, and you’ll absorb a feast of information along the way. View the mighty cannons that boomed during the siege, or stop into one of the plentiful cafes, should you need a little refreshment before continuing your journey. St. Columb’s Cathedral, which dates back to 1633, towers over the walled city, and is one of the city's most significant historic sites. Its dreamy spire contains a set of bells that have peeled out melodies here since 1638, making them Ireland's oldest.
