Bettna

Bettna is a locality situated in Flen Municipality, Södermanland County, Sweden with 412 inhabitants in 2010. It is also a parish with the same name.

Bettna is located at a similar distance from Flen, Katrineholm and Nyköping (20-30 km) and about 5 km from the nearest village of Vrena across the Nyköping municipal line. The boundary goes a few hundred metres from the village entrance by national road 52. The topography around the village is generally flat with occasional rolling hills and little elevation is covered when travelling to either of the three nearby municipal centres. It lies at roughly 30 m above sea level. Bettna is also adjacent to the lake Yngaren and also has other lakes in its vicinity.

The oldest part of the church was built in the 12th century. Its organ was approved by the Swedish king Gustaf III shortly before his assassination in 1792. The organ was reconstructed in 1988.

The Swedish post-impressionist painter Nils von Dardel was born in Bettna in 1888.
