10544 Hörsnebara           Discovered 1992 Feb. 29 at the European Southern Observatory in the course of the Uppsala-ESO Survey of Asteroids and Comets.
The small Gotland parishes of Hörsne and Bara joined to become a single parish in 1883. In Bara, there is a church in ruins, one of few such ruins on the island outside Visby.
