256813 Marburg           Discovered 2008 Feb. 11 by E. Schwab and R. Kling at Taunus.
Marburg is a German city, first mentioned in 1138. A castle and Germany's oldest gothic church dominate the medieval cityscape. In 1527 the oldest protestant university in the world was founded, which has operated the Marburg Observatory (later renamed Gerling Observatory) since 1841.
