10128 Bro           Discovered 1993 Mar. 19 at the European Southern Observatory in the course of the Uppsala-ESO Survey of Asteroids and Comets.
In Bro, a small parish on Gotland, there is among other things an old cairn from the bronze age. More than 40 meters in diameter, it is said to be the burial site of chief Baldur.
