Terrestrial enclosure

The terrestrial enclosure was a massive domed area within Watchtower class space stations primary hulls. The enclosure was landscaped to mimic Earth-based environments and had an artificial sky that could be programmed to simulate day or night. In the 2260s, no other non-planetary base had anything like this facility for Starfleet and civilian personnel. 

The terrestrial enclosure in Starbase housed Fontana Meadow, the high-speed maglev tram and Stars Landing commercial and residential district amongst other facilities and establishments.
