The cache is not at the above coordinates, but you will need to start here first!
Welcome to Historic San Juan Capistrano, or HSJC for short. This is part of a mini series of multi caches that are placed at historic areas in San Juan Capistrano. It's been a while since I've done a new one, and I've had great feedback in showing historic areas of San Juan Capistrano. This is an easy two stage multi.
According to the historical marker, what was built on this site in 1877? Enter those 3 words as 1 word into certitude below for the final coordinates. Fun fact, if the gates are open, you may tour this historic building on the grounds. The cache is a short walk away and is not inside the grounds. Both WP1 and the final are accessible 24/7, even if the gates are closed. Use stealth and BYOP. Be carful if you are walking to GZ.
You can validate your puzzle solution with certitude.
