Wells Fargo Center is a 129 m (423 ft) office building in downtown Sacramento California. Construction on the skyscraper began in 1990 with completion in 1992, and yet stands as the tallest building in the city. The building occupies a 2.3-acre (0.93 ha) city block, and features a five-story granite and marble walled interior within a clear glass atrium. The project was developed by William Wilson & Associates in partnership with Crocker Properties. The architect was Hellmuth, Obata and Kassabaum (HOK).
