Parish and church
Aars belongs to Aars Parish, and Aars Church is located in the middle of the city. It was built in granite in the first half of the 13th century. When Aars had become a station town and began to grow, it became necessary to expand the church in 1921-22, where it was also whitewashed as it is now.

The city also has an evangelical charismatic free church, which was founded in 1989.

At Søndergade 44 is Museumscenter Aars, which was established in 1999 by merging the cultural history Vesthimmerlands Museum from 1935 and the art history Himmerlands Kunstmuseum from 1980. In the center there are both permanent and changing exhibitions with the area's archaeological finds and contemporary art. There is also a permanent exhibition about Johannes V. Jensen, who took the initiative for the cultural history museum already in 1920. The new buildings from 1999 were designed by architect Jens Bertelsen in collaboration with Per Kirkeby, who is one of the many artists who have left their mark on the city with sculptures and buildings.

The Danish Museum of Contemporary Art stores things from the Danes' everyday lives for the last 100 years. It was opened in May 1994 in a disused farmhouse and now has approx. 1200 m² exhibition.

5 km southeast of the town is the reconstructed Borremose fortress, a refuge castle and later village from the Iron Age. In Rævemosen 4 km east of the city, the site of the Gundestrup vessel is marked with a memorial stone.
