Cologne - By Samuel Taylor Coleridge

In Kohln, a town of monks and bones,
  And pavements fang'd with murderous stones,
  And rags, and hags, and hideous wenches;
  I counted two and seventy stenches,
  All well denned, and several stinks!
  Ye Nymphs that reign o'er sewers and sinks,
  The river Rhine, it is well known,
  Doth wash your city of Cologne;
  But tell me, Nymphs! what power divine
  Shall henceforth wash the river Rhine?
