Londonderry – also known as Derry is the only completely Walled City in the British Isles. The walls were built in the 17th century as defences for early seventeenth-century settlers from England and Scotland. It is well worth the visit if you’re based in Belfast and want to make an excursion out of the capital. Situated around 62 miles away, the trip would take around 90 minutes. Derry will keep you busy with its beautiful riverside setting, its several fascinating historical sites and the numerous museums, galleries and theatres, as well as thriving musical and literary scenes.
