8682 Kräklingbo           Discovered 1992 Mar. 2 at the European Southern Observatory in the course of the Uppsala-ESO Survey of Asteroids and Comets.
Kräklingbo is a small parish on the Swedish island of Gotland. Located here on a hill are the remains of a fortification nearly 2000 years old, the biggest in Scandinavia. From that hill many of the medieval churches on the island can be seen.
