20243 Den Bosch           Discovered 1998 Feb. 25 by E. W. Elst at the European Southern Observatory.
Den Bosch (s-Hertogenbosch) is the capital of the province of North Brabant in the Netherlands. The city flourished in the 15th century, although it was nearly completely destroyed by a catastrophic fire in 1463. The painter Hieronymus Bosch lived almost his entire life in Den Bosch.
