Derry/Londonderry is Northern Ireland’s second-largest city, built on the western bank of the River Foyle and enclosed by one of the best-preserved sets of city walls in Europe. The city has a distinct mix of Georgian and Victorian terraced housing within and around the walled city, alongside post-war social housing estates and contemporary new-build developments spreading outward into areas such as Strathfoyle and Shantallow.
