Tucson, Then and Now

This website came out of a desire to share one of the most interesting parts of Tucson, the Barrio, with the public at large. The Barrio (sometimes referred to as Barrio Historico or Barrio Libre) is one of the oldest parts of Tucson that is still extant, and excellent examples of traditional Sonoran architecture abound. Bounded, roughly, by Main Street to the east, Cushing Street on the north, Stone Avenue on the west and 17th Street to the south, the Barrio is quite compact, yet extremely varied; some buildings have undergone significant restoration, while others sit abandoned.
A thoughtful architectural analysis of the Barrio structures is far beyond my capabilities. In its stead, I present a rather large 'then and now' photo essay of the area (and a few other parts of Tucson).
The 'then' photographs were found through the Library of Congress, with most taken in the summer of 1980, some in 1937, and a few from the 1880s. In all cases, I believe these photos are either in the public domain or are not eligible for a copyright (many were commissioned for the Government, making them ineligible for copyright protection).
The 'now' photos were all taken on 20 December 2002. In all cases, these photos are copyrighted, and can only be used for non-commercial purposes, provided proper credit is given. Commercial use is expressly forbidden.
With that out of the way, let's get started. While I tried to keep the individual pages small (under 150kBytes), some may take a while to load, so be patient.
