Old town.

For an interesting take on old Santa Fe, see http://www.common-place.org/vol-03/no-04/santa-fe/. The map from the British Library is the earliest known of our little town, drawn by Joseph de Urrutia in 1767.

Also at that site, scroll down for a view of the St. Francis Cathedral--you can see how FRENCH the structure looks right there in the middle of downtown.
