About Calles and Carreras:
In Bogotá, the calles (Cll), or streets, run east-west, and the carreras (Crr or Krr), or avenues, north-south. The streets are numbered progressively to the north and to the south and the carreras to the east and west. You can always orient yourself by facing the Eastern Hills: North is to your left, and south to your right.
Every few years, the city renumbers the calles and carreras. La Candelaria’s streets used to be numbered 11, 12, 13, 14, 15, etc – which seemed logical. But, to make things simpler, the city’s planning geniuses renamed them 11, 12, 12B, 12C, 12D, 12E, etc. On many buildings, you’ll see two address plates: An older one, with a diagonal line through it, and a newer one with the current address.
