Tucked into a corner of Old Town, the so-called Historic Jail is a small thick-walled adobe with a barred window and a heavy door. It looks the part of a frontier holding cell, but it never held a prisoner — it was built as part of an early restoration to add Wild West flavour to the streetscape.
It takes two minutes to look at and makes a good story to tell. Free, no signage to speak of; you find it by wandering the side streets off Main.
