Gretchen Park is an orbital exotic botanical garden built in 2237 by Robert Gretchen dedicated to his dying wife and research assistant, Margret Gretchen. At the height of the station's popularity, it received over two million guests per year. However, by 2315 enhancements in force field and biological containment technologies allowed exotic plants to be kept on Earth's surface, ending bans and making the park obsolete. By 2320, Gretchen Park was completely abandoned.

As of 2425, the Gretchen Park was turned over to Sa'ren Sk'llian and the Kit Biosphere Restoration Project.

Planning for Gretchen Park began in 2234 six months following the terminal diagnosis of Margaret Gretchen, wife of famed exobotanist Robert Gretchen. The final architectural design was selected in January 2235 with construction beginning by March 2235 and ending on 7 July 2237. The park officially opened to considerable fan fair on 1 October 2237.

Marget Gretchen would die in 2236. In accordance with her wishes, her body would be used to grow some of the plants at Gretchen Park in a process known as Human Composting. A dedication plaque was placed on the main grounds near the lake in a flowerbed.

Park attendence grew steadily until the Federation-Klingon War of 2256 when the station was closed due to damaged by orbital debris. Repairs were completed in 2258 and the park reopened.

A major renovation of the station's amenities was performed in 2270. This change allowed visitors to book stays in hotel suites, gain access to after-hours demonstrations or classes, and provide hosting for conferences. This would also be the last major overhaul of the station's operations and engineering systems.

Robert Gretchen passed away on 15 January 2273. Like his wife, he was similarly interned through composition. The board of trustees and the Societal Preservation of Roses, Etcetera continued management of the station.

Attendance began falling steadily from its peak of two million visitors per year in 2280 to just 500,000 per year by 2300. Efforts were made to revitalize and draw crowds, including opening the park as a venue for weddings and parties.

In 2315, following improvements in force field and botanical containment systems, laws were changed to allow large quantities of previously banned exoplants on Earth. Several botanical gardens, conservatories, and zoos began importing specimens which before could only be seen at Gretchen Park. Attendence at the park entered a free fall and by 2320, the board of trustees was disbanded and the park shuttered.

The station was handed off to various property management groups following the shutdown. These organizations sought to revitalize or retool Gretchen Park into various ventures including hotels, schools, and even an embassy. However, these projects failed to manifest in part due to the aging infrastructure and specialized rooms which did not follow modern Federation modular design, greatly impeding renovation efforts.

In 2425, the station was handed over to the Federation-run Kit Biosphere Restoration Project.

Broadly, the station configuration aligns with the following table:
