Triangle Metro Zoo (originally Zoo Fauna) was a privately owned and operated 40-acre (16 ha) zoo that was open from 1998 until 2006. It was located in Wake Forest, North Carolina, United States. The zoo originated from Larry Seibel's long experience in breeding exotic animals, and was opened in 1998. It was situated in a heavily forested area astride a small stream. Its name derives from the area of North Carolina in which the zoo was located, which is called "the Triangle" because it comprises the three larger cities of Raleigh, Durham, and Chapel Hill.
Shortly after the zoo opened in 1998, the barn containing the gift shop and restrooms burned down, and was never rebuilt. The owner cited lack of facilities at the zoo due to this fire, which prevented him from putting up a permanent sign on Capital Boulevard, as one of many factors that led to the lack of funds for the zoo and its eventual closure.
