Tombstone

Tombstone is a city on Earth, located in Arizona, which is part of the United States of America. The city was the scene of a famous gunfight on October 26, 1881 at the town's OK Corral.

The Melkot people recreated the city on their planet, intending to execute Captain James T. Kirk and his landing party for trespassing on their planet. However they were impressed with Kirk's handling of the situation, and decided to welcome Kirk and the USS Enterprise (NCC-1701) to further visit their planet. (TOS episode Spectre of the Gun).
