35 Treasury Street - I only had a few hours the day I was in St. Augustine in February of 2008. I had not been there previously and had not done any research on what I should see (I knew about the fort but didn't make it there) so I wandered around random streets. After researching after my visit I found that I had somehow managed to hit many of the important buildings. Unfortunately I only took one picture of this building. For a detailed history of the church visit their site at http://www.thefirstparish.org/history.html.
