I read with great interest the article about the Fort Oglethorpe hospital. We have had very pleasant experiences with a similar structure at a closed Army post.
(IN THE NEWS: Commissioners express desire to help protect historic Fort Oglethorpe hospital)
Fort Benjamin Harrison near Indianapolis, or locally known as Fort Ben, was declared surplus by the federal government. Hundreds of acres were transferred to the state for use as a state park. The remaining campus was repurposed into a very successful economic development area.
The old Fort Ben post hospital was turned into a hotel managed by the state park. Simply an amazing building that preserved the architectural elements of the era. Most likely very similar to the hospital at Fort O.
I highly recommend staying there if you travel through the area.
