I first came across the Old Saint Augustine Village Museum on a field trip, of sorts. It was a one hour field trip that an introduction to American Literature class took (walking over) from Flagler College to the Village, the significance being that Ralph Waldo Emerson had stayed at the Prince Murat house for a short while, while recovering from an illness, and wrote a poem about Saint Augustine. Apparently, he liked it, and it was interesting to see the little alcove where he stayed.
The village consists of nine historic homes whose artifacts are in keeping with the era that they were built. The Murat home is the earliest, from the late 1700's, and a turn of the century home, complete with fascinating early appliances and furniture, is the most recent. It is, more than anything, a place to sit on a bench next to a fountain in a narrow, cobbled alley between gorgeous historic homes and appreciate the uniqueness of our little town. Small exhibits are very informative and all the employees are extremely energetic. Tours are available, but you may also wander in and out of the homes as you please, which might be even more fun if you're growing tired of the many tours around Saint Augustine.
I love recommending the Village to visiting relatives, especially the more mature ones, and making people realize that if they keep walking past the Casa Monica, they'll find our town's biggest little known attraction. It's an unexpected treat if you've already seen the Castillo several times and think you've seen all there is to see here.
