Kata Gård is a private farm church from the Viking Age. Archaeologists have made sensational finds here during their excavations. The church's crypt is possibly the oldest surviving room in Sweden. The church ruins were named after a woman's skeleton: At the end of the Viking Age, Kata ruled over the farm belonging to the church. The excavations revealed that Varnhem was Christianized a century before the rest of Sweden. An information building was erected at the excavation site: Here, modern architecture is combined with walls that are thousands of years old. Some tombs, including Kata's tomb, can be seen through panes of glass in the floor.
