The Gazebo At Fort Benjamin Harrison
This is a wonderful little gazebo right outside the entrance of Fort Harrison State Park. It is part of the Fort Harrison Inn and is for rent. I can't stress enough that this is for rent. If you try to use the gazebo for free they will charge you and will contact law enforcement to press charges for trespassing.
This location is totally worth the money! There is a pond nearby to add to locations for pictures and free parking.
Some couples rent a park shelter and get married inside the park. Keep in mind, on a really nice day, it can take a lot time to get into the park, so plan ahead!
