The Holmby Runestone, listed as DR 328 in the Rundata catalog, is a Viking Age memorial runestone with an image of a ship that is located in Holmby, which is about 2 kilometers southeast of Flyinge, Scania, Sweden.
The Holmby Runestone has an inscription that consists of runic text that is upsidedown in an arch that is over a depiction of a ship at sea. The stone is made of sandstone and is 1.11 meters in height. It was discovered in the wall of the southwest corner of a church tower around 1667. Before the historic nature of runestones was understood, they were often reused as construction materials for roads, bridges, and buildings. The stone was removed and raised outside the church in 1908. The inscription is classified as being carved in runestone style RAK, which is considered to be the oldest style. This classification is for inscriptions where the ends of the runic bands are straight and there are no attached serpent or beast heads. The inscription is dated as having been carved after the Jelling stones.
It has been pointed out that the image of the ship has an ancient form with beaks fore and aft, and thus may depict a symbolic ritual ship and not any known Viking Age ship type. Other inscriptions with similar features which may depict ancient, symbolic ships include DR 77 in Hjermind, DR 119 in Spentrup, DR 258 in Bösarp, and DR 271 in Tullstorps. Other runic inscriptions from the Viking Age which depict ships include DR 220 in Sønder Kirkeby, DR EM85;523 in Farsø, Ög 181 in Ledberg, Ög 224 in Stratomta, Ög MÖLM1960;230 in Törnevalla, Sö 122 in Skresta, Sö 154 in Skarpåker, Sö 158 in Österberga, Sö 164 in Spånga, Sö 351 in Överjärna, Sö 352 in Linga, Vg 51 in Husaby, U 370 in Herresta, U 979 in Gamla Uppsala, U 1052 in Axlunda, U 1161 in Altuna, and Vs 17 in Råby. Three stones, the Hørdum and Långtora kyrka stones and U 1001 in Rasbo, depict ships but currently do not have any runes on them and may never have had any.
