Temple Square is a ten acre (40,000 m²) complex located in the center of Salt Lake City, Utah, owned by The Church of Jesus Christ of Latter-day Saints (the Mormon or LDS Church). In recent years, the usage of the name has gradually changed to include several other church facilities immediately adjacent to Temple Square. Contained within Temple Square proper are the Salt Lake Temple, Salt Lake Tabernacle, Salt Lake Assembly Hall, the Seagull Monument and two visitors' centers.
