One of the great things about old Spanish colonial towns is all of the interesting architectural details everywhere you look. Many of the colonials near the center of San Cristobal are well over 100 years old, though it is hard to know how many are actually from the time of the colonization. There are quite a few adobe houses which are newer than 100 years old as well.

A courtyard for Ladies and tea in their roses
Where are they now, one only supposes
