What's in a name? A lot, as far as this town is concerned. Whether the citizens call their town Derry or Londonderry is a question of political and religious belief: it is Derry to Catholics/Nationalists, and Londonderry to Protestants/Unionists (at least when the conversation takes a political turn). Media, wanting to be neutral, uses both names.
The original name of the town was Derry. In 1613, however, the town was given to a London company and renamed Londonderry. This new name was not the only change: the town was completely reorganised and a thick wall was built around it; Catholics were banned from the inner town and had to build their houses outside the walls. Londonderry remained the official name until 1984 when the city council changed its name to Derry City Council.
On January 30, 1972 Derry was the scene of a violent (Vorfall, Zwischenfall, Ereignis) incident known as the Bloody Sunday: at a peaceful Catholic demonstration for (Bürgerrechte) civil rights, 30 men were shot dead.
The Guildhall built in 1890 was destroyed and rebuilt several times. It is a cultural and civic centre where concerts, plays, exhibitions and meetings are held.
