400 West Market is a skyscraper in Downtown Louisville, Kentucky. The 35-story, 549-foot (167 m) high structure was designed by architect John Burgee with Philip Johnson and was completed in 1993 at the cost of US$100 million. The building, originally named Capital Holding Center, was later renamed Providian Center and AEGON Center as the business was renamed and sold. AEGON left the building in 2010, and the building was renamed 400 West Market in 2014.
Currently the tallest building in the state of Kentucky, the building is constructed of reinforced concrete, as opposed to the steel construction usual for buildings of its height. A distinctive feature of the building is the 80-foot (24 m) high Romanesque dome which reflects the building's original name of Capital Holding that is illuminated from the interior at night. The upper floors of the building are also illuminated at night. 400 West Market's lighting is changed from the usual white to a combination of red and green from Thanksgiving Day until New Year's Day.
The skyscraper has 633,650 square feet (58,868 m²) of leaseable space for office and 18,787 square feet (1,745 m²) for retail.
The original owner of 400 West Market was a limited partnership which consisted of Hines Interest, as a general partner, and Japanese limited partners. In April, 2004, David Werner's investment group purchased the building.
There is a statue in the plaza of 400 West Market of Alysheba, winner of the 1987 Kentucky Derby and a 1993 U.S. Racing Hall of Fame inductee.
